In other words, the core of the problem is that women would choose the “wrong” people to marry, so they should be forcibly restricted in who they can marry for the good of society.
That is fucked up.
Given that we already live in a monogamous society, and 1) the Middle East is significantly more fucked up than our society, and 2) the proponents for polygamy will not make the necessary ideological trades in order to avoid the outcome of becoming more fucked up like the Middle East?
It doesn’t bother me.
Because the argument is generally based on “rights” and “freedoms,” the option “only let men marry stacks of women in proportion to the rate that women marry stacks of men" is not really on the table.
Oh, and, if I were in charge of the country, I would tax junk food. For your “how anti-freedom is Mitigated Chaos” calibration purposes. Additionally, I would ban new cousin marriage out to the second or third degree.
Edit: Oh, and I suppose you don’t support racial anti-discrimination laws, do you?
