My Mom always taught us: "If you don't have anything nice to say, don't say anything at all." I teach the same to my kids (that and "never make a promise that you don't intend to keep.")

I agree with Ron, the anonymity factor allows cowards to act tough. I believe the harsher and more brazen the comments from people on the internet (e.g. Youtube comments) the faster such guys would wet themselves if they were required to say such things face to face with whomever they're criticizing. Pitiful. I've wondered what kind of losers spew such venom toward people they don't know.
