So, we have a group with extremely strong innate biases, and a majority of them are part of a political ideology built around hatred of the out-group.

This is referring to an innate hatred of men.

Contextually, as he's said before, this is the kind of hatred where (as he's said before) women want to kill and abort all young boys, including their own sons; and that is the primary attitude of all mothers.

As far as I can tell, you just were biases. Which, frankly, I don't even think is true, but you're looking at a statistical pre-disposition to be affiliated with that in-group. I haven't heard you say that all mothers want their sons dead.
