debates are fine, but some just love to attack without provocation, just because of boredom or lack of cognitive skill. It gets better the more you deal with it, but sometimes enough is enough.

If someone says I have bad taste in shows or insults ME personally for liking them, then that's one thing. But if they say a show I like sucks... Well, it doesn't bother me one bit. Chances are, I probably hate some show they like, too.

we dont all like the same stuff! simple as! but sometimes its just rude as!

I think i get more passionate over couples than when people cuss the shows i like.

if they say something bad about my favorite show, i let them say it. 'cause it won't make me stop watch it anyways! :P
i have a lot of friends that doesn't like (example!) supernatural. even though they haven't seen it. not even a clip! x) but i don't care if they like it or not. 'cause i still love it! and that's kinda what matters x)

If its just random hate and rudeness, it annoys me.
But if they have a valid point and its not immature its fine.
