I can say many things like jealousy, prejudice, selfishness, and whatever else there is to say; yet I see that no one has brought up the point of denial. Everyone can talk about greed, fear, ignorance, and whatnot, but if you bring it down to a personal standpoint, from which all hatred comes from, denial seems to me to be the root cause for all the things you guys are talking about. If people realized they aren't by any means perfect and invincible, they might also start to realize that when people do make attacks on themselves, the attackers are just being fools. That's kind of a coarse argument, as it is very hard to explain, but hopefully some of you will know what I mean.
I don't know, so this is my signature.
