There are three solutions.
Transwomen/men only allowed to access their own sex, transwomen/men allowed to choose and third spaces.
Women said "we want to protect single sex spaces because men can exploit the grey area and we aren't particularly comfortable with males who have transitioned for various reasons". They did NOT say transpeople must ONLY use their own sex.
Women said that they understand concerns about privacy and proposed the third space option. That was rejected as being unacceptable because ultimately it turns out that validation by women is the goal, not access to the space.
Its all about the use of women, not the use of the facilities.
We have been talking about this for years. At first we were TOLD there was 'No Debate'. We didn't get a choice. Well screw that. We are worthy of being listened to.
Ultimately this about demanding something and then having a tantrum when equality of privacy dictates that trans people need to consider the feelings of the opposite sex whether they like it or not.
I'm way past the 'being nice' to people who have been absoluete shit heads to others wanting to find a reasonable workable third solution.
The words at this point are 'tough shit' you've burnt through all possible good will.
