YouTube is a video site...

...not a fight club for pete's sake. 0.0 It's "broadcast yourself", not "fight with others".

Another reason why i use the "Comment Disable" option on my account.

I support YouTube as a happy video site, not a fight club.

Edit time:

I just made a video message about it here in my YouTube account: [link]

Edit time 2:
Golly! Look at all the favs! The "bad" comment problem on YT will always be on the rise, sadly. But look on the good side, you can always remove the bad comment(s) on there... (on your videos, actually.)
