MIdge, it's the standard situation in the NHS that a woman can request to be seen by a female HCP, or have a chaperone if this is not possible.
Whether or not we should have mixed sex or single sex wards is a related question,but it's not exactly the same.
The activists here are obviously, to sensible eyes, trying to remove the right to single sex provision. But that's not their framing - they are explicitly saying that the right to ask for a female HCP would remain, and even flimflaming some related nonsense about single sex wards by saying they would insist that the male person in front of you was female.
That's the issue here, as far as I can tell.
