a perfect solution, assuming we're talking about marriage and paternity/maternity - if you're a true feminist, defined of course by equality, you#re agree with this:
1) men have a right to opt out of parenthood responsibilities if they do not sign a contract before a certain time, perhaps 12 weeks, after inseminating a woman. if a man changes his mind in this legal system, he's ****ed. if a woman does, she is allowed to and she can have an abortion. we should both be allowed to change our minds, because hey, it's not far to force people into shackles of economic slavehood for 18 years.
2) marriage should have an automatic requirement for a prenup, just like in france, not just to oppose the idea that all marriages are about property, but to stop people from exploiting one another. either this, or have marriage not about property whatsoever unless specified otherwise.
a truly egalitarian system for parenthood and marriage, right here. for men and for women. there is no bull**** cultural, traditional or patronising argument towards women here. the controversial idea of giving men mechanisms they can use against the interests of sometimes ill-intending women is a good thing in that it is consequentially against such women, not all women, naturally, or else you'll expect women to oppose this system as if they're all selfish!
