I'd guess around 95% of the feminism board threads are about trans issues, and there is a nasty, underlying whiff of transphobia in many of the posts. When I think of all the issues that could be discussed on the feminist boards that affect women - rape, violence, disability, racism, war - and yet none of these topics get much interest. 87% of austerity directly affects women, and 80% of women are mothers. The conviction rate for rape is 6%, domestic violence 5%. Mums living in poverty are having to turn to sex work to feed their kids. According to the Family Rights Group, domestic violence is the most common reason now for social services to start family court proceedings, and victims of DV are losing their kids because they either 'failed to protect them from witnessing DV' or their kids are at risk of future emotional harm, and a lot of those kids are having to have contact with their violent dads when they don't want to. Women seeking asylum here are being separated from their kids and being sent back to countries where they are risk of rape and murder. Universal credit is going to plunge more mothers and their poverty. And so much more!
Sometimes things like this are discussed on the feminist board, but 8 out of 10 threads are about trans issues, and are hostile to trans people. So I am not suprised.
