He's not JUST suggesting we encourage monogamy in society (WHICH WE ALREADY HEAVILY FUCKING DO).
Women's wishes are in this framework, irrelevant.
It's inherently dependent on a worldview in which the wishes of individual women do not matter, because these men cannot see women as serving purpose other than the advancement of men's genes.
They are, at their core, inimical to the idea that women fundamentally deserve to have the same opportunities as men, because their view sees that as interfering with a natural order.
It's formed around a lack of having the specific sexual framework they desire, in which other men are not getting more sex simply for being more attractive to women, in which women are to exist for sex alone.
Attractive men are "Chads", attractive women are "Staceys", and Staceys fuck Chads because they're "sluts".
The pathetic fuckers want that to end, because they see Staceys as their own, and Chads as despoiling them.
You might note that this is the polar opposite of sexual revolution.
