> having seen what some of the women in my life go through re: abusive behavior online, I also understand the hair trigger
Even from your own words, it sounds like the heart is not in the reaction, but what people are reacting to.
I am moderately mouthy on social media. I get a much, much smaller level of pushback than similar women do. When I do, the level of respect is higher, and I almost never get my credentials questioned. But I regularly see women with much stronger credentials get those inspected and/or dismissed. Just yesterday I saw a woman with a relevant PhD getting talked down to by some random guy. And then when she made a separate post about her frustration with reply guys and how she was thinking about leaving Mastodon, some different random dude told her to "get a live".
Historically, we spent thousands of years keeping women in "their place". That was partly legal, but mostly social. We've solved the legal stuff in the US, but only recently. (E.g., states only started to outlaw marital rape in the 1970s, and it wasn't fully outlawed until 1992.) It should be no surprise to anybody that the social mechanisms did not magically evaporate the moment we passed some laws. And I think one of those social mechanisms is the disproportionate negativity women get from men when they are not in "their place". When they have the audacity to act like they know things and have valid opinions just like men do.
If you want to read more on this, Manne's "Down Girl: the logic of misogyny" is a very careful examination of the mechanisms and their effects. If you're looking for "the heart", I think that's a good place to continue your search.
