The idea that misogyny among men is responsible for keeping women out of STEM fields contrasts starkly with the considerably higher representation of women in STEM in highly misogynistic countries and lower representation in more equal countries.

I've also rarely encountered commenters on hacker news saying women cannot succeed in engineering, and it's downvote heavily in the rare instances it does appear. You claim it's present in this thread, in your previous comment, yet don't link to any instances of this alleged disparagement. It strikes me as the kind of statement that stems from assumptions rather than concrete observations.
