I'm an utterly orthodox feminist in the political or social sense: I want equal rights for women, period, and I vote that way. I support social programs that help women and children; I'm pro-choice, in favor of anything that makes it easier for women to raise their kids, with or without men, in conventional or unconventional family units.
But do I think the world would be a better place if it were run solely by women? No; not any more than I think a solely patriarchal model is an ideal.
