I and a lot of my colleagues just want to do our work without being forced to participate in regular struggle sessions.
Instead, the signs could be changed to simply state "Restroom". Sure, one might have urinals and the other a tampon dispenser, but anyone can use either and everyone could agree to be adults about it.
I imagine transitioning is a very emotional and vulnerable thing to happen. Hence it being awkward that someone apologized for misgendering isn't unreasonable at all. Advocating that no-one should even do that would be unreasonable. But just presenting "this happened, this is how it made me feel" is a very natural thing.
From such a presentation general rules cannot always be derived. That is not the point of such a presentation. The point is for someone who is having feelings to have those feelings heard and recognized. Maybe that can lead to a bit more understanding for people who were never in such situations.
It seems like a waste of time to make these meetings all-hands company wide. But don't dismiss these activists just because they pushed for an all hands meeting. It wasn't a good thing to push for, but people get things wrong sometimes. Having been wrong is not the same as always being wrong.
It is also useful in pushing out "troublemakers". People that will not call BS on the unsubstantiated political claims are also less likely to call out corruption/nepotism/inefficiency of the middle management.
In the long term the company will stagnate and die, but we live in such a wonderful time of government bailouts, low interest rates and desperate investors, so it may take a long time to unravel.
