Blimey, now you're asking!
Why do men hate women?
I think that deserves a thread in its own right.
Lots of people think the original hatred was due to men's feeling of inadequacy and jealousy about not being able to give birth to children. Freud inverted this womb envy as penis envy. Later on this was overlaid with all the lies men told to justify their enslavement and dehumanisation of women, like women are crazy bitches, malevolent, liars, inferior, etc.
I'm not sure whether that's true or not and tbh I don't care. I don't care if men hate us or not, I just want them to stop killing us. And each other. And to stop preventing us from taking our rightful place in society as full human beings.
