She was in a tech forum where a woman was complaining about her experience at a company. It amounted to this woman having a perception that she was not being valued as much as a male colleague and was immediately jumping to the conclusion that it was sexism. My wife jumped in and suggested that from the sound of things, it sounded like there may be some other things going on that this person could work on and that it may have nothing to do with sexism etc..
The other people in the forum, including men, crucified my wife for those statements. This along with her daring to suggest in other women in tech forums, groups etc. that not every piece of feedback that is not positive is sexist led her to be banned from several women in tech organizations. Many would not even tell her why, but if they did it was for "being harmful to women" and "suffering from internalized misogyny" among other things.
Given her experience alone, not to mention other things we have all seen in the community none of this is surprising to me. Ironically, one of her concerns when she saw the "micro-agressions" etc. trend take hold, beyond the fact that she felt it was trying to fix one wrong with another, was that it would lead to this...and here we are.

What I do personally is to just avoid all of these people.
I have the impression it's harder to avoid them in California because people are particularly brainwashed over there - which is one of the reasons I avoid California as well.
