FWR = Feminism and Women's Rights was the original name of this topic area. Womens Rights is still in the URL. Longterm users still think of this area as FWR.
FWR has been under special moderation rules for some time because of issues relating to sex and gender (updated sticky that has previously had several names).
Over the years there have been lots of lots of complaints to MNHQ that the feminism on FWR was mean and that it was impossible to talk here without being expected to know about feminism. This had led to previous incarnations of the board being renamed and split several times but it still all ended up under Feminist Chat.
Last year, there was a renewed slew of complaints about meanness and that the board was dominated by discussion about legislation and other events concerning sex and gender or asserting women's human rights and not allowing them to be erased in service of a gender ideology.
As you'll see in Site Stuff, there was a mass of discussion. MNHQ decided that Feminist Chat would be the main board for the topic and that those of us discussing this live issue would be hived off to the Sex and Gender topic. This would create a 'safe space' for all of those women who wanted to discuss feminism but didn't want to discuss sex or gender ideology.
However, relative to how it was, Feminist Chat is now tumbleweed. So much so, that MNHQ is now moving threads initiated in Sex and Gender over to Feminist Chat.
That's a partial and editorialised potted history but Site Stuff post the Forstater decision is where you'll see all of the arguments around this.
