>>every man finds little girls sexy
Sorry but I'm a guy and I totally fail to find little girls sexy. I find womanly curves very sexy and you have to wait for sexual maturation for them to develop.
Now of course little children are cute, but that's a totally different thing, at least for me.
As for misanthropy, I don't dislike humanity as a whole, just the fact that benevolent feelings (generosity, empathy, etc) are usually parochial, whereas negative feelings (hate, fear, contempt) are more general. This is what causes people to help their neighbors but don't give a shit about millions of suffering foreigners.
