The old "gentlemen's agreement" in loos, that we let in the really tiny number of transwomen with dysphoria worked,
because they just wanted to "pass",
so they stayed very quietly in the background and they were so few in number anyway.
It's different with the much larger number who want public validation and to dominate womens spaces their way
Now we have the increasing number of exhibitionists and predators too
and it is no longer a matter of transwomen not wanting to use the mens loos,
but now demanding - as of right - access to womens prisons, hospital wards, refuges, sport, awards & grants
Hence, many of us decided we need to return to strict single sex segregation,
at least until this whole self-ID idea has been binned and the aggressive TRA movement with it.
As I've posted before "We gave an inch and they took a mile"
That's what happened when we were kind to what was a very tiny subgroup of men.
Now, we need to push for 3rd spaces, so trans people can feel comfortable & safe.
Where these are not yet available, make the mens facilities unisex, not the womens
because the need is to cater for a subgroup of men who feel vulnerable, but at least have the size, strength, muscle of a male body.
In the case of prisons, then a separate wing in mens prisons, closed off from the rest of the prison, as for other vulnerable offenders.
