I don't understand why some people feel the need to be such ignorant assholes and insult people just for liking something they don't like.

For example, I was watching this video here:

and I saw a comment from a hater:

This also applies to other things besides MLP. I can't go on a freakin' video of a band I like without seeing a comment from some asshole saying like "this band is gay" or "this band sucks." I mean, I have no problem with someone not liking something i like, but there is no fucking reason to be a prick like that and insult people for no good reason. People need to learn how to stop being so close-minded and ignorant and stop being friggin' assholes!!!

Also, I understand that a lot of people do that just to "troll" people, but that's just stupid...
