I read the thing and as usual from JB it's word salad, unrelated points being linked because why not.
The main things for me in that piece are:
The idea (fact) that biological sex is in any way important in humans is wrong oppressive and bad.
Anyone who thinks that biological sex us relevant to anything at all is either a religious fundamentalist, t*RF or some other sort of baddy.
Strangely the fact that 99.9999% of the world knows exactly how important sex is and what it means for how people are treated/ expected to behave is... As usual not even slightly alluded to. The ONLY people who are the worst of the worse for saying sex matters are t*rfs aka women.
It's very interesting that.
Anyway. There you have it from one of the most famous long term proponents of this philosopher.
And JB is a philosopher. As such it's their job to think about all sorts of things. In the end it's a highly intellectual and academic discipline that is not to do with being grounded in the day to day.
So her theories and arguments. Perfectly more than fine as a point for consideration, debate. To provoke questions and challenge attitudes etc.
The fact that what should have been interesting thought experiments and challenging concepts got consumed by the criminal justice system etc.
Well that's another question entirely. It wasn't her having behind closed doors meetings with govt etc. Or somehow getting the department of health to tell NHS to have single gender wards but LIE to the public about it bloody years and years ago.
