You cannot compare sexism against women to that of sexism against men. There is far greater sexism towards females than males, and that should be our focus at the moment.

There are only two real valid points I can see for sexism against men:

1. It is not socially acceptable for a man to hit a woman, but it is fine for a woman to hit a man.

2. Women get child custody much more than a man does, but the logic is quite clear in this one, as the mother is the one who raised the child.
