Because men don't care about women's suffering. They really don't. They have been socialised to see women as "other", as inferior, and so they have been raised without any intrinsic empathy towards the position of women.
This is so true, and is why I doubt the efficacy of the liberal feminist program to 'educate' men about sexism. In order for men to care about sexism, they would first have to care about women as significant beings, and it's obvious that most of them don't.
men have been treating women outrageously for centuries. it is them who should be asking nicely. nicely and humbly asking us to continue to interact with them and to believe them when the say they want social justice for women despite many of their actions showing quite the opposite.
ITA with this. Seriously, the horrendous shit that men have been getting away with and still get away with all over the world in regards to women, who have done nothing to them but give birth to them, nurture them to adulthood and invest untold amounts of physical and emotional labour in their wellbeing, for them to turn around and say we're being unfair by demanding that they stop treating us like shit, just underlines the fact that they think we exist entirely for their gratification.
