Having already written to my (female, Muslim, Labour) MP to say they have lost my vote after 47 years over the trans issues and this ludicrous delay, I will be writing again if the guidance isn't laid before the HoC in May.
I come back to my original thinking on this issue: about seven years ago, I realised I didn't understand it and thought it was because my scientific knowledge was lacking and that it was very complicated. I read about it and did understand it, and was incredulous that the ideas its proponents embrace could have gained such traction.
