Ah, I agree with you, sort of. But I don't think it does any good to generalize this either. I have nothing against the Biebs or 1D, hey, let them do their thing and let their fans enjoy it. Can their fans be immature? Of course they can, but there are many smart people who enjoy their music, too. Just like there are smart people who like MCR, but then there are those few immature bitches who ruin it for the rest of us. But not all of us are like that.
Also whoever came up with the MCR fandom being "non-judgemental" was full of cow feces. There are many people in this fandom that I've made awesome friends with, and they've all been very nice; but then there's the occasional fan who just makes me feel like shit because I guess I'm not the "typical MCR fan".
I wish we could all just go frolic naked on fields of sunflowers and bask in the glory of rainbows and friendship. Love and tolerate, dudes. Love and tolerate.
And, I will just say, I hate it that our taste in music defines who we are.
