The argument against what she says is that GRA reform has no bearing on what spaces people use. But that is missing the point that in a society where everyone knows that any man, regardless of how he presents, could legally be a woman because he might have signed some forms, it will become much more difficult to challenge males in female spaces. After all, as TRAs tell us, no one checks birth certificates when going into a toilet. So women are going to feel much more uncomfortable challenging males generally and even if they do the male could just claim they have a GRC and the woman be dismissed as a transphobic bigot.
This is exactly what happened at the WiSpa in California, where lo and behold the 'woman' turned out to be a convicted sex offender.
And apparently GRA reform was pushed through in Ireland by stealth on the back of marriage equality, so people didn't even know it was an option.
And it's not just toilets anyway is it? It's prisons, hospital wards, refuges as well.
Maybe it needs spelling out a bit more clearly, but it seems obvious to me?
