Whatever ground the TRA lobby gains, it's merely a starting point. That is another fact that the numpties in politics won't acknowledge. This is not the end game, it's just the opening moves.
The only fair, human rights based solution is third spaces. Which meet everyone's needs but require government to have the guts to say firmly, we respect your choice of identity, we respect your need for different provision and safety because we get male violence is a huge issue, and here is the plan to enforce third space roll out nationally with funding, but your sex is not the same as your gender, and single sex spaces are for that sex only. End of. Line is here. X number of refuges will be gendered, X will stay single sex. And there will be robust protections for women to protect single sex spaces and to back up organisations who have to deal with someone of one sex trying to use facilities for the other sex, instead of their own sexed facilities or the additional ones provided. And the GRA goes because what's the point, self ID as you like. That will be absolutely respected. It just won't be regarded as legal status of the opposite sex.
Cue: Rage.
