Females seek genetic variability in their offspring through polyandry. Mating with only one male carries the risk that paternal genetic problems may affect all of their offspring.

The 'Patriarchy' which they rage against actually the traditional family, held in place by monogamy vows. These provided an illusion of reassurance to a husband that his genes were in all of the children he was providing for.

But, it would appear that when women have political power, they will engineer legislation which favours female reproductive preference - polyandry. The most egregious example of which is 'no fault' divorce, brought to us courtesy of NAWL, the National Association of Women Lawyers.

This allows women to 'trade up' to a higher value man, at any time, and without penalty. Achieving this as a social norm requires weakening of monogamous marriage vows, until these are functionally meaningless from a male perspective, although protecting female security through the family courts.

Female security is further bolstered by employment advantages through 'progressive' initiatives such as AA, EEO, ESG, DEI, based on quotas rather than merit. The work of Roy F Baumeister on Sexual Economics indicated that, for a man, having a 'good' job was his main trading card in the dating market.

For each woman 'preferred' in employment, there goes another man who may never attract a woman, pair bond, and form a family. Meanwhile, there's a woman whose position places her in proximity to high value men, with her comparative financial security allowing her to be increasingly 'choosy'. All men beneath her pay grade are rendered invisible.

'Sexual Harassment' legislation keep them invisible. By law.

Meanwhile, there are generous welfare safety nets for women, should they make 'mistakes', or choose not to make use of the opportunities afforded them in a skewed system.
