I think people should be able to say, "I don't like such and such..." or "I hate bla bla bla...."

But they cross the line when the blatantly say, "You-know-who is bad," or "This guy sucks."

Everybody has their own opinion, but when someone says to everyone, "My opinion is right and you all are losers, who don't need anything!!!" It gets me agitated.

And it doesn't just happen about guitarists (though this is where a lot of it happens), but about just about everything (if you don't believe me, check out the politics threads that happen ever so often in open discussion...)
