We've all done that thing before. "Ew, you like Twilight? Ew, you watch yaoi? Ew, you like Justin Beiber? Ew, you like the color brown?"
That's cool and all, you don't have to like things that others don't. But people have no right to blatantly insult someone because of something they enjoy. Just because you don't like something doesn't mean that someone is wrong for disagreeing with you.
Sorry for mini-rant. Can't have enough of these stamps on DA
