Edit: There was also some sort of false outrage ending in some people brigading Rome 2's scores because someone lied about how you can recruit tonnes of female generals as Rome or something like that. Then it turns out they cheated it either with photoshop or mods and the only female generals you can hire are really low percentage or 50% as that one African weed nation or whatever.
Either way it's pretty dumb.
Oh no, it's way dumber than that.
Youtuber ArchWarhammer decided he wasn't making enough outrage and manipulated the game until he got 5 female generals, and then started claiming that the devs had issues a secret patch that caused all generals to become female and how this is an outrage, where is muh 'historical precision'. Then to make sure this was an actual shitstorm and not a mere shitbreeze, actual literal Nazi newspaper The Daily Stormer (that I am not going to link, and you probably shouldn't search for) issued a piece about how in Total War, white soldiers are being replaced by women and black people (though obviously they used a pejorative term).
Did people look at this and calmly check the information? Of course not, that would be sensible. Instead they started review-bombing the game about how Rome 2 has no historical precision (Gauls in Arabia? Just fine. Women in my game? OUTRAGE), how it is SJW, how it is dragging politics into their precious gaming (which is a laughable complaint, since culture and politics might as well be the same thing), and so on and so forth.
Things got even more inflamed when a CA community manager said that there were no changes, the game was working as intended on that aspect and no plans were being made to change anything, and that if they still didn't like that to mod it or stop playing. Obviously this led to more OUTRAEG and cries for the community manager to be fired.
In short, youtuber and literal nazis inciting outrage, plus a huge load of misoginy and racism because of course.
