I agree with dick and table.
I only keep decent people in my life, so I don't really know any nasty people.
In the world outside my sphere of friends and family, it's my opinion that the crappy people far outweigh the decent ones. As in the ratio isn't even close.
Also, I disagree with the poster who said people are mostly good. When you boil human beings down, I think they're selfish, inconsiderate, and not particularly other-directed. I believe there are basically equal numbers of jerky men and jerky women as well.
That has always been why I'm attracted to so few females. It usually doesn't have anything to do with looks, career, money, or what kind of clothes she has on, it's that, exactly like men, most women just suck, and aren't worth spending 5 minutes around.
The upside to this is that I'm truly happy to be around my friends and family, all of whom I consider good people.
I just basically ignore everybody else.
