From what I could tell, this afternoon's witness objected to the two questions on the publicity for the AHF screening:
Is it really harmful when men self-identify as women?
Is it progressive for doctors to change young people's bodies in order to affirm their 'gender identity'?
(I'm paraphrasing here because I didn't get the full questions, but that's what they seem to be.)
The screening was due to be in December 2022. That's when the GRR Bill was on its way through the Scottish Parliament, and its two main proposals were getting rid of the need for a medical opinion for a GRC (i.e. self-ID), and lowering the age for a GRC (making it more likely that younger people would so identify). So the two questions, assuming I'm in the right ball park, are exactly the two questions I'd expect to see framing a responsible discussion of sex and gender in that context.
