I’ve got one like that as well. Lovely woman, very smart, religious Christian, married to a professor. Seemed perfectly sane until he took an appointment at (here we go again!) University of Wisconsin, Madison.
A few years ex post facto, stimulated by the election cycle apparently, all this feminist drivel from her starts appearing on my Facebook page. Never heard a peep of any of it while we were close friends, and we were close enough that I would have.
