The LP started saying self ID'd transwomen could apply - ie people who are not legally women. There is no exemption under the Equality Act for gender ID (YET!! That'll be their next step though) - therefore at the moment allowing self ID transwomen - not legally women - onto AWS could be legally challenged.
Interestingly the proposed amendments to the GRA not only include removing all three criteria, it also includes changing gender reassignment to gender identity under the equality act.
It seems, from the outside, to be fairly moot. Because gender reassignment does not actually have to involve anything. You can just say you are considering becoming a transwoman.
But, there is no way activists would have asked for it if it wasn't going to be beneficial.
I suspect it will mean that a very male presenting man who has no intention of transitioning can claim a female identity as a purely administrative tick box.
It's sort of like that now. But there are at least cultural protocols to defy.
This way, those cultural protocols will simply wear away over a few years.
If anyone says the word woman, an automatic response will be, which kind? No one will blink an eye, it will be entirely normal.
Then it will be, ooh one of the old fashioned kind! An actual, biological woman. We haven't had one of those for ages.
