To the ardent feminists, a simple question -- do you believe the world would be a morally superior place if there was no biological distinction between men and women -- i.e. there was only one gender?
I think ardent feminists are focused on making realistic changes to reality, i.e. working with the reality that we have a great diversity of sexual identities, gender identities, and gender roles, rather than try to fight against it. Fair treatment of women and minorities does not entail erasing all differences until we are a uniform grey.
