It's entirely believable. Classic projection.
To respond to the OP's point, if this refers to some of the more outlandish threads on this site in which women are blamed for absolutely everything, I'm less than convinced that all or even the majority of those posters are necessarily women. There's a clear infiltration from some of the murkier incel/women hating areas of the internet, and those posters tend to be pretty transparent.
That said, it's undeniable that some of the worst misogynists are women, and that those women are desperately anxious to keep other women in their boxes. It's personal, and its political, and it's not new. To cite one example, why any women would oppose her own and other women's basic right to vote, as the anti-suffragists did, is beyond my comprehension. It's similar to denying yourself a vote for your own head of state. It can only be assumed the people who do this don't want these fundamental, democratic privileges because it's too much hard work, or they would prefer others to do the heavy lifting of thinking for them. The same applies in reverse to very capable men - men who claim the higher salaries and bulk of the CEO roles - who apparently can't manage simple domestic tasks in the home.
Put simply, it's learned helplessness. But these are the ones determined to foist their views on others. Anyone can exercise the right not to vote, but it was anti-suffragism which wanted that right removed from anyone with a vagina.
Same now goes for the women who want our protected spaces shared with men. They don't get to consent for me.
Yes, in the past decade or so I agree we've gone far backward, given we'd made (minimal) progress in the 20th century. But in the overall scheme of things in the history of our species, I suspect it's very much a case of same shit, different century.
