Lot of truth here.
Mother's attachment to their offspring.
The looser attachment between mating adults.
The lose attachment of fathers to their offspring.
The distinction between (women and children) and (men) as categories.
The distinction between single men (dangerous) and married men (safe).
All of these represent biases at least as strong as and as influential as racial bias. But they don't talk to us about this, nor do they try to push against it.
Nobody crusades to have mothers care for their children less, so they are biased in favor of them less, and to make the bias between the genders more equal.
While men pushed for universalism, feminism is deeply grounded in these innate biases. Feminism is basically
why should men have more when women are more important?
"Equality" is just the crowbar, invented by male philosophy, used by feminists to constantly insist upon a shift in the social foundations so the unspoken biases always tip in favor of women.
"Equality" always benefits women, because of the aforementioned innate human biases placing "women and children first".
