There is a reason why comradery seems to be male oriented, does not seem to come natural to women (I've not verified this so take it as a weak theory)

That's probably why "girl power", "girls have to stick together", and "believe all women" became such powerful memes, when it would be totally laughable to guys. They overcompensate and shout that all women must be allies to all other women, because they know it's not true. Women fake it until they make it.

A lot of women are going to be removed from manager position by other women based on the vitriol they can't help themselves to spew.

But feminism doesn't say "You must hire this specific woman to a manager position", it says "You must have at least half of all managers be women, (even if far less than half of the qualified applicants are women)". So maybe there would be infighting, but the women who get booted out would just be replaced by other women, and the women forced out would just find employment elsewhere, for the same reason.

Firing 15 women and 5 men and hiring back 15 men and 5 women from high positions in your company would get you articles written about how sexist you are, regardless of why those women were fired or how much you have to scrape the bottom of the bucket to find other women to replace them. So yes, maybe some specific women will lose out and screw up so badly they won't get rehired by some other company desperate to find even vaguely qualified women to hire, but women as a whole just can't lose.
