I hit my post size limit on the last one so I excluded that bit, especially since I think it's a bit of a distraction. (Whataboutism basically.) But I'll gladly address it:

Say we found out that, after ensuring the existence of women's locker rooms, assaults on women using locker rooms are cut by 90% relative to when only unisex locker rooms are available. (This is what the little data we have seems to suggest.)

Let's say that assaults on men using locker rooms, however, stays the same.

This would mean assaults on women are cut by 90%, and assaults on men unaffected. That's a starting point, and one could then tackle the issue of men assaulting each other, if this is a widespread issue. (I don't know about it being a widespread issue, but maybe it's just not on my radar.)

Could assaults on men *increase* due to sex segregation? It's possible to imagine, theoretically, because perhaps the occasional presence of a woman in the unisex space acts as a deterrent. (Less chance of assailant and victim being alone.) It's an interesting thought, but seems like a stretch to me. Absent any data to suggest that there is such an issue, it can't possibly justify abolishing sex segregated locker rooms.

IMO the best solution, in general, is two sex segregated regions/rooms, and then within each there should be cubicles for people who prefer not to be seen nude one way or another. There could also be a smaller set of individual cubicles in a more open unisex room or area, as a third choice.

This kind of arrangement would massively decrease issues no matter what choice society makes w.r.t. trans people's use of locker rooms: A transwoman could use one of the cubicles in the men's region, and be relatively safe, or they could use a cubicle in the women's region, becoming much less likely to cause distress to women there who don't want to be exposed to a male stranger's naked body.

Really the primary issue right now is that it has literally been normalized for male people to expose themselves to women, saying "I'm a transwoman so even if I have a penis I get to use this locker room." That's just not OK. (See YMCA issue linked earlier where exactly this happened. A few years ago I would have never believed that things could get this bad.)
