Look on the bright side of this idea:
Due to hypergamy, women will tend towards plural marriage with the few alpha males who don’t give a rat’s rear end for feminism or feminists.
The feminists will be left alone, or having to settle for the beta/gamma males who aren’t worth jack. And increasingly, those men are refusing to marry.
Within two generations, we could be done with feminism for good - the feminists will have seen what their stupidity bought them, and they’ll realize that they brought the results on themselves.
Excellent!
My initial thoughts are that men will be more likely to have multiple wives than the reverse.
