I've always found it fascinating how one person will have their "unpopular opinion" and then suddenly it's the most popular opinion in the world. Everyone jumps on the bandwagon. Then, after a few days/pages/whathaveyou, suddenly it's the stupidest opinion in the world and all the sheep have moved onto new opinion. I'm as guilty of it as the rest of us. It's a fascinating quirk of humanity, part of our desire to fit in. Trouble is, eventually it will turn ugly because there are also people out there who have nothing better to do than try to piss people off.
I have abandoned many a fandom because of the gang mentality I see on so many of them.
And that's where it gets frustrating, because there are also some very smart, funny, clever folks trying to have fun, thoughtful conversations going on. you just have to wade through a lot of shit to get to them, and you have to get there fast before it devolves into "my favorite character is better than your favorite character who is horrible and evil and stupid while mine is heroic and amazing and perfect".
