Well, some recent hindsight analysis (during the eridu radical-feminist debacle) allowed me to notice that it seems highly likely that nearly all female feminists I've encountered in person with common knowledge of such were mostly of the kind that had one or few strong very bad near-type personal experiences with men, or many small but memorable such near-type experiences. The kinds you'd probably expect from a stereotypical scenario of "The Father is Master and Law of the House" or a poor waitress working late shifts at a café on the same street corner as a strip club.

More generally, I'm starting to suspect that most extremists might be Generalizing from One Example, e.g. that antinatalists are unhappy with their lives and kind-of assume that everyone else is.
