I think the distinction that people don’t make is that…

1. For a woman, sometimes you can get a man to fight for you, so it makes sense to get him to take on all that risk himself.
   
2. For a woman, the upper body strength distribution is almost bimodal, so it makes even more sense not to fight and send a man instead if you might end up fighting a man.
3. Society often treats women and their violence as harmless.  (The flip side of the glass ceiling.)

So if you have a high stress situation consisting only of women, isolated from society and from men, it may well get violent.

Do we have any actual statistics on rates of violence in all-female societies?

All girls schools seem the obvious test case. A quick google gives me one article saying that violent bullying is worse in all femae schools, but other studies say the opposite. Confounders are a problem obviously. But at the very least the numbers  are close enough that there isn’t conclusive evidence. There’s some interesting stuff saying that bullying for not conforming to gender stereotypes is less bad in single sex environments, but that doesn’t necessarily say anything about the total levels
