Sorry haven't had time to read all posts so far, and suspect I will just be repeating what others have already said.
to quote OP "to discuss the hundreds of ways in which sex - and gender roles - impact on women’s lives, irrespective of their views on sex and gender" as a suggestion just doesn't make sense. If you are discussing the hundred ways sex and gender impact on your life then how you view either of these will be reflected in what you want to say about that impact.
Are we able to have discussions on an issue where those with a different view on sex and gender can each comment and not have someone say in response but because I believe sex and gender mean that ... means what you have said make no sense.
So long as threads allow people to respond directly to previous posters this will always be an issue.
For this not to happen mumsnet would have to set up a different type of forum, where (for instance) a topic is announced, everyone who has a reponse sends them in by a fixed deadline, then mumsnet publishes them on a thread closed for responses.
And even if you someone created this artificial divide how would you stop the issue of sex and gender coming up?
And what I dont understand is that there are quite a few topics posted that aren't specifically about women as biological females, and quite honestly they get a very low response.
So either this means those who say they want other issues really dont, they just want to complain about others having different priorities to theirs, or they are telling mumsnet the mere existence of these threads on issues resulting from women being told their sex isn't real, is somehow so hostile and alienating, they cant even bring themselves to add comments to threads that aren't directly related to sex and gender.
What would this supposed "solution" solve?
And who is it that is asking for it. Has MNHQ provided any figures ie is this a request coming from over 50% of those using the FWR forum.
At the very least there should be a poll.
You would think mumsnet would be celebrating, having been mentioned as a source of support in the Maya case.
In a few years when all this push for self identity fades away and people return to their senses, MNHQ will be able to show that between 2014(?) and 202? they played a positively role in helping stop the erasure of women's sex based rights.
