Sorry, afternoon home learning lessons were calling so I have only just seen the question you asked re Swim England.
I think these guidelines may now have been withdrawn, but it was guidelines aimed at increasing trans participation in swimming (which of course is a good thing, exercise being good for health, etc), but which basically said that if anyone was unhappy with a male bodied person in the women's changing room (or vice versa in the men's) then that centre user needed to be educated out of their incorrect view.
And also that if a centre offered single sex swimming sessions, then anyone trans should go to the one that matched their gender identity - hence the need to be ready to educate females who saw males in their women only sessions.
There was also hypocrisy on what it was suitable to wear in the pool.
You may need to do some education work with other centre users who may be concerned when sharing a space with a trans person, especially if a trans customer looks to have different physical characteristics to the gender they are identifying with i.e. a male to female trans customer who has not had top or bottom surgery may still look like a male to others* and conversely with female to male trans customers.
*like the person in the deleted picture from thread one, perhaps?
There was a thread about it at the time and I think it may have been the start of Man Friday, but I could be wrong.

Looking at it now it looks quite tame, but it was enough to hook me in. I'll go and catch up with the rest of the thread now - if the question has been answered in the meantime, I apologise for repeating.
