Why do guys become misogynists?

what causes someone to hate women so much. I don't get it. you were made from a woman, times have changed where women are now doing everything a man does and more. all guys, even misogynists can answer. and girls if you know someone like that, have they explained why they feel that way? this is something that I don't understand at all because of all the circumstances. all help would be great.
