Agree that if you weren't around at the time of the split imposed on us because nice feminists complained about having gender critical / sex based rights feminists being so unkind, it isn't clear.
So you could ask MNHQ what they thought they were doing.
Nobody apart from a few that MNHQ chose to listen to why there was a split.
The url of this forum makes it clear it is the original Feminism and Women's Rights network, and as over time it became one of the few forums on line where women could come and talk about being gender critical and not be banned, without an actual vote or anything, sex based rights was the main believe expressed on posts.
But some didn't like it. Complained and MNHQ created Chat for them.
So FWR (under MNHQ's ditzy heading) by default was for gender critical feminism to be the basis of the forum.
This has come up on other threads, that those participating on FWR dont want every thread to start with having a long discussion about why sex based rights, what about trans rights, why are you being unkind.
Or that they come on FWR to go back to ground zero all the time, or feel obliged to explain why they are GC / SBR feminists.
Nobody voted on this. Nobody chose the label.
That was MNHQ in response to a few complaints, and to be fair, some who thought it would be easier to have that shared believe as the jumping off point, not the point.
