I also posted this on tumblr, where there is a lot of Blaine hate... I know that many of the users here just dislike him or think he's boring, but this was written mostly for tumblr - I just wanted to share it here too. Here's a warning: this is not Kurtofsky/Hevans friendly, and it has definite tones of Blainofsky/Klaine. Okay, so I'm doing this so that some of the people who hate/dislike Blaine and ship Kurtofsky or even Hevans will see why people don't hate Blaine. If you don't feel like reading, please don't. I don't want to cause you physical pain, so, just leave this alone if it will.

I've felt like doing this for awhile. I really have. I understand Blaine hate. I really do. I don't agree with it, but I understand it. I feel like a lot of the haters don't understand why some people love him though. I feel like many of them believe that Blaine love stems from a boring cliche, the fact that he's "perfect", unreasoned thinking, Darren Criss himself, his solos, or his looks. I just want to let people know that there are more reasons for loving Blaine and more reasons for not hating him. I'm going to address some of the most common reasons that people hate Blaine, and try to put in why I don't after each one. I don't think that this will convert anyone who's really truly thought about it and still doesn't ship Klaine or Blainofsky or whatever because they don't like Blaine or they don't think he fits with either, but I just want to get this all out.

Blaine is perfect
This one is obviously untrue. I'm sorry. It just is. I know that some people think it appears that Blaine can do no wrong, but he has. He's done a lot of wrong. Maybe some of the other characters believe that he is perfect, but he is not a perfect character. He's extremely oblivious at most times. He also is much too afraid of taking chances. His skills with tact on several occasions are also extremely questionable. He's wrongly asked Kurt to blend in more on several occasions. His communication and relationship with his father is horrible. It doesn't seem like he's even sure on his father's stance in their relationship. I have a defense to throw in there, but I'm just pointing out his flaws right now. He can easily take things personally, like when Kurt was upset about Blaine wanting to try dating Rachel, when he snapped at Sandy in ANON, and when he yelled at Dave in the hall.

Blaine is flat 
I know where this one is coming from. Most of Blaine's screentime revolves around him singing solos, and ALL of it revolves around Kurt. I disagree with him being flat. His past is neglected. The writers haven't given it the respect it deserves, but it's still there. He's had the crap beat out of him for taking another boy to a school dance. He transferred schools and blames himself for running. His relationship with his dad kind of sucks. He doesn't always understand why being individual is more important than being safe. He thrives on performing and on the sense of friendship and acceptance that he seemed to be lacking in his old school. He's questioned his sexuality, and been very hurt when he didn't get support. He has a complex web of reasons for acting the way he does.

Blaine is overrated
I feel like I understand this one more than all of the others. There is a lot of Blaine fangirling, Klaine love (sadly not as much Blainofsky love), and Darren Criss stanning. I get that it's weird he's so popular. Sometimes, I don't understand it myself or even wish he was less popular so people would stop saying how overrated he is or how annoying his stans/fans are (yes, it annoys even me, who is a Blaine fan, when some of his fans are irritating or close-minded). I also feel like he gets more hatred than any other character (except for maybe Finn or Jesse) in direct retaliation to his popularity. I actually feel like he does deserve the love he gets because of how hard he works to try and help people and try and be a good person, despite the things that hold him back, but it is strange to me that he is so popular. I mean, I feel like this is one of the few things that the fandom has gotten right in its popularity. I feel like St. Berry deserves a lot more love, Quartie, etc., and it confuses me that Blaine has gotten so much. I realize that people may love him for the shallow reasons, and that's why he actually is so popular, which does make sense to me, but for the reasons that I'm a fan of him, I think the love he gets is fine.

Blaine doesn't understand what Kurt/Dave are going through 
This one seems extremely presumptuous to me. Blaine knows what it's like to be bullied and feel like you're not being accepted. We know that one for sure. He knows what it's like to be afraid of showing who you are because of what other people think, but doing it any way. He also knows what it's like to have a crush that doesn't reciprocate your feelings (this relates to Kurt's earlier crush on Blaine himself and, if Dave is actually crushing on Kurt, Dave's crush on Kurt). He knows what it's like to be judged because you like boys and not because you like singing or because you like to smile or for everything you are that isn't your sexuality - heck, he even left his old school because of that. He personally went to tell Dave that he wasn't alone, saying that it's a hard thing to come to terms with, implying heavily that Blaine struggled with coming to terms with it himself, and it was, very much so, further reinforced by his simple acceptance that Dave wasn't ready to come out yet or to accept help, showing that Blaine most likely knows exactly how Dave is feeling at that stage.

Blaine is arrogant
This is another one of those reasons that I understand why people would say, but I disagree with. Blaine is confident in his abilities, yes, but he's not arrogant. As soon as he got called out on the amount of solos he was getting, he had a sudden epiphany that he actually was getting an unfair amount of solos. It wasn't malicious. When Blaine went to Kurt's father about sex, he didn't say, "Look, I know how you should be raising your kid better than you do," he said, "Look, I might be overstepping, but I'm worried about Kurt." Most importantly, in Silly Love Songs, Blaine showed his vulnerability and that he isn't arrogant. He was afraid right before he was going to serenade Jeremiah, and he had to be reassured by Kurt. After the performance, he thought it was too much. When he was rejected, he didn't get angry or defiant - he simply took the rejection, and seemed to realize why he was being rejected. Blaine even said himself that he has no idea what he's doing. He knows how to act it out in song, but when it comes to life, romance, etc., he's still trying to figure everything out. He's not AFRAID to admit this either. He doesn't pretend like he's something he's not. He's always honest about who he is, even if it risks people finding out that he's not perfect, or he's not as confident as he appears to be.

Blaine is oppressive
I don't disagree that this is something Blaine has trouble with. I understand that people would hate him for telling Kurt to blend in or thinking that the kilt was a bad idea, but I don't hate him for this because of the reasons he's been this way, and he seemed to get over it. What do I mean? With his advice with the Warblers, that's simply how the Warblers work. Trying to stand out wasn't going to do Kurt any favors. It was made obvious by their reaction to Don't Cry for Me, Argentina. Blaine doesn't run the council or the show choir (even if he gets all the solos), and he was simply telling Kurt how it works there. Those who have an issue with Kurt not being able to make it about him, need to take it up with the Warblers, not with Blaine.
Now, on to other matters of oppression. People seem to forget his past. They seem to forget that he was scared enough to transfer and that he STILL regrets it. We don't have the gift of a flashback to Blaine's old situation, and we don't know nearly as much as I would like to, but we do know about his past bullying, even if it was only ever mentioned. I feel like if we had seen him being beat up or shoved or cursed at, people would be a lot more sympathetic towards him and not so easily forget what he's been through. Another thing about this is this seems to be an argument used by many people who ship Kurt/someone else. Do you honestly think that Dave would suddenly have no fear and face everything even more head on than Blaine when he's so afraid of coming out that he turned to physical violence to try and keep up his machismo? Do you honestly think that Sam would be fine with going around and doing whatever despite any consequences if he were with Kurt when, if he is bi or gay, he's made jokes about balls being in his mouth to deflect and said quite pointedly that he isn't gay? Neither Blaine, Dave, nor Sam (if Sam is gay or bisexual) are as brave as Kurt. Blaine is the closest though. He's the one who's out. He's the one who's willing to try to go to a dance with the boy he's with even though the last time he brought a boy to a dance, he got the crap kicked out of him. He's the guy who didn't want attention drawn to him and his boyfriend because of a kilt (something said boyfriend's father was also concerned about), but NEVER said a word again after Kurt decided that he was still going to wear it. Going back to an earlier statement I made, I think that Blaine is getting over his fear. He had a huge moment when he stopped just standing around at Prom, and went and danced with Kurt after Dave left the room. He seemed to be tired of cowering like a scared puppy, and it seemed like he decided to screw what was holding him back and just be there for his boyfriend because Kurt needed him.

So, there it is - I doubt that I defended him as adequately as he deserves, but I tried. I don't know if anyone's opinions on him will change because of this, but I felt like getting it out there any way. Stay lovely, my wikiers.
