In your experience what are the most retarded communities on the Internet?

I probably try to stay clear of the worst ones, but it seems that Youtube comments can make me feel physically sick and reduce my IQ for a while. Sometimes I think "let me check out what people are saying about this cool song", and much of the time there are a bunch of dribbling retards spewing insults and other incredibly stupid comments.

Yahoo News. Every story, no matter how seemingly innocuous, has its comment section filled entirely with people telling each other to go fuck themselves. It can be kind of amusing in a dumb way, but it also makes my head hurt.

YouTube is pretty awful, too, but it isn't as uniformly bad.

my class sometimes,some people are so incrediably frustrating ,its makes me wanna blow up some times.

VGCHARTZ.COM/Forum is pretty bad I hear.

Very creative and unpredictable.

most (though not all, I found a few that arent crap) forums for Football teams or Bands are horrible, full of trolls that seem to only register to flame the team/band that the forum is for.

sometimes im amazed how many religous fanatics can end up in one class....but yeah on the internet ,youtube is incrediably childish...its mainly people saying crap about bands

Places where the users constantly use "retarded" or "gay" in place of "stupid" or "bad".

CNN

everybody who posts thinks their geniuses and are giving helpful advice, and the amount political correctness sickens me, also they turn EVERYTHING into a political debate

Just like in real life, the fanatical religious boards are a cesspool of idiocy, inbred down syndrome , and retardation.
