I don’t think women are much less faithful to men than men women.
Insofar as statistics can be trusted, women initiate about two thirds of divorces, but men commit about two thirds of adulteries.
If we took away women’s legal advantages (abolish child and spousal support, etcetera), they’d probably initiate divorce about as often as men, perhaps even less often.
I don’t think it’s necessary to change or reduce women’s status to that of big children or slaves in order to keep them loyal to men.
What I advocate is full legal equality between men and women.
However, once they have a taste of true equality, many of them may prefer to be treated like big children, where they have more positive rights (freedom from poverty and so on), but fewer negative rights (freedom of choice and so forth), where they’re under the care or guardianship of men (fathers, brothers and/or husbands, etcetera) and/or the state.
Perhaps we could give women a choice, collectively/democratically or as individuals, whether they want the same rights as men or exchange some negative rights for positive ones, but they shouldn’t be given more of both like they are today, nor should they be given fewer of both, like property or slaves.
I’m not a misandrist, but I’m not a misogynist either, women are of course different in some ways, different strengths, weaknesses, needs, but they’re not better or worse.
