I think it's a really bad idea, but @Bordois is almost certainly correct.
Mumsnet had somehow passed me by through the years when my children were younger - I remember an article way back in time in one of the weekend newspaper magazines with Justine excitedly explaining why she was setting it up. It all seemed to be about the best buggy and her managing to tag along at the back of the crowd in the great Internet gold rush. I rolled my eyes and gave it a swerve.
Fast forward to the run up to the GRA consultation and my benign area of twitter (Archers, occasional news stories a few NHS doctors and chat) started having more concerning tweets. I credit Dr Christian with alerting me to the word terf. Dr Haddock (who he?) reared his unpleasant little head. And a link took me to this board. I was appalled and amazed at what I found, particularly regarding children. I could not believe that in the U.K., in our NHS, children were being given puberty blockers and put on a trans pathway because they had been judged for playing with the wrong toys. I had been completely unaware this was happening.
I never really took much interest in feminism and didn't count myself as one. I'm lucky enough not have experienced sexual abuse, the flashers that hung around my girls school were widely derided and we felt safe in a gang with our hockey sticks so we never really thought more deeply about it. In twenty years as a midwife I mostly thought feminism seemed to neglect mothers and small children, pushing to get women back in the workplace without considering their desire to care for their own children and the needs of small children.
It seemed to be mostly about overpaid women in jobs like banking and the BBC complaining about not being as overpaid as their male counterparts. Working in a female dominated area, in the NHS with its nationally (then, before devolution) agreed payscales I have never experienced sexism at work. I regret to admit as a midwife I didn't know enough about domestic abuse and how to address it, thankfully midwives are now taught to be alert for the signs and to question women and be proactive, the profession has caught up with the times in that respect.
So finding this board has been a great education for me. Of course the GRA consultation was hugely important and the ongoing discussions and events leading to Maya Forstater and the latest judgement. But there is so much more here, and my eyes have been opened to many other issues, and I'm very grateful for the wider education. I have two daughters, young adults now, and lots of the discussions that happen on this board are relevant to their lives.
Splitting the board will mean that ignoramuses like me will be unlikely to find it anywhere near as helpful, they probably won't find the other section (isn't that the plan?) there will be a greater tendency to think "oh well that's a different issue, it doesn't affect me" or whatever.
I just think it will lead to a slow death of FWR. Which is probably the plan.
