It all comes down to equality of opportunity vs equality of outcome. When there is equality of opportunity women choose different fields...often (but not always) because of different interests. Equality of outcome forces people to do things that they may not have an interest in. And that is before you get into interests vs natural talent and how that does or does not affect ones success in a field. On a fundamental l…
Every woman I know with a genuine and deep interest in STEM subjects has had to deal with some level of toxic/sexist/whatever stuff in their life, and they persevered and dealt with it because they weren't going to let it get in the way of their passion.
It might sound harsh, but I don't feel terribly concerned about keeping these displaced women in STEM; if their interest isn't strong enough to overcome a bad environment, then maybe they just weren't that interested to begin with. That's not a bad thing, it just means that they misjudged the interest:difficulty ratio.
Of the cases I know of personally, most of these women ended up in a job working fairly close with STEM stuff, writing manuals, doing graphic design, etc, and are perfectly fine with those jobs.
To be clear, I'm not accounting for cases where an entire university or business or whatever is made up of toxic sexism, but that's been pretty uncommon in my experience in the US.
Women of STEM: if you've got a bad environment, do something about it! Tell your higher-ups, talk to people directly, seek a different position, endure what you can, and for God's sake stand up for yourself.
tl;dr the implication that most women in STEM can't handle a toxic work environment without giving up entirely doesn't seem that progressive at all
NB disclaimer, most people I know are computer scientists, plus a few mathematicians, so maybe engineering is different
