She was talking about this just now on my way to work. The discussion started just after 8.30. A lot of opposition to people with penises in female prisons. It's a good job I was at traffic lights when she threatened to throw someone out of her studio for talking about "cis" women at the end of the debate. I gave her a round of applause for stating that there are transwomen and women and that transactivists don't get to change the language applied to women just because they want to change gender. Men and women are still men and women.
