I've just got back from a holiday with a British friend who now lives in France.
She's been aware of my views on self-ID and was and is generally supportive of the GC view.
However, one bar we were in had women's and men's toilet cubicles but within a unisex toilet, so the sink area was shared. I ended up washing my hands next to a man and when I got back to my friend I told her and said I thought it was uncomfortable. She said she didn't see the problem with this set up, and that it's quite common in France to have to walk past men with their penises out pissing in France to get to the women's cubicles. She says that it's a shock but that you get used to it, and that it's not a problem. I said I don't think women should have to get used to it, and I didn't want it happening in Britain.
But is it true that this is the situation in France and there are no problems?
