Genuine Q - why does self ID harm women?
A GRC doesn't really do very much practically day to day so what difference does selfID make to anyone not trans?
Even in prison having a GRC doesn't mean you automatically go to your new genders prison. The MOJ decide.
Trans people can change their gender in passport, drivers licence, NHS gender markers, almost all documentation for daily life without a GRC. They can just make the changes.
A GRC just means people get a new birth certificate which means they get married and have death cert in changed gender.
And a trans person even with a GRC doesn't get automatic entry to single sex spaces - these are protected by the Equality Act.
You talk about men in women's changing rooms but you don't have to show your birth certificate to go into a changing room so whether there's selfID or not, anyone can walk in anywhere. Having a GRC doesn't really make a difference.
The biggest threat to women is... shocker... cis gender men. Men are the biggest threat to women www.unwomen.org/en/what-we-do/ending-violence-against-women/facts-and-figures
You'd argue that transwomen are men - but really, if a man wants to abuse a women or child he doesn't need to get a GRC and pretend to be trans. He's got ample opportunity to do whatever he wants to do!
There's no evidence from other countries selfID harms women. www.openlynews.com/i/?id=21757767-4909-4844-922f-41903ff042f8
I'm sure theres examples of a few transwomen harming women, there will be, but they're the exception not the rule. If a man who is not trans wants to harm someone, he will, he doesn't need a GRC!
So really, what impact does selfID have on women? When having a GRC doesn't actually do anything on a day to day practical level.
