morningrunner, it's incredibly difficult for services to prove they are excluding transwomen as a proportionate means of achieving a legitimate aim. Toilets, changing rooms, even prisons apparently don't meet that test. DV and rape crisis orgs currently can meet the test but even women's aid are reviewing their policies in the wake of Miller's report. Women's orgs have to make a really good case to exclude transwomen from services and if they do, they have to try their hardest to make alternative provision (so diverting increasingly scarce resources from their core aim of helping women).
By changing the wording of the EA from 'gender reassignment' to 'gender identity', it's not only transwomen who 'live full time as women' (whatever TF that means) who need to be accommodated in women's spaces and services if at all possible, it's non-binary Steve who is Stephanie on Thursday afternoons. No thanks.
We don't know exactly what Labour's manifesto will say yet. This idea as far as I can tell is lifted straight from Miller's report. The other thing Miller recommends wrt the EA is to remove the single sex exemption where a transwoman has a GRC. I would not be at all surprised if Labour go for that too.
The current govt. has pledged to review the GRA to 'de-medicalise' the process of getting a GRC and I cannot imagine any party that is likely to get elected ditching that pledge. This is the self-declaration thing.
Changing one word of the EA might seem minor and not worth fighting but it is. It's one of three legal jigsaw pieces that, put together, spell the end of sex-based protections for women altogether.
With an election looming, it's the best time to write to your MP, and your candidates from other parties. Now is the time they are least complacent because they all want your vote. If you have written before and got a boilerplate response, now is the best time to write again.
