I don't know whether it's worth pointing this out again: the current, and increasingly dominant, line I'm seeing from prominent trans activists is that
- sex is a social construct and
- transwomen are not only women, but female.
With someone like Travis, I'd say it's fair to assume 'transfeminine' or 'femme' people will conveniently fall into this bracket too.
What concerns me, then, is that if we allow men like Travis into women-only changing rooms (which then become 'gender-neutral' - in reality, unisex - changing rooms) we have no coherent justification for excluding men from other spaces they're not currently allowed in.
Why? Because if Travis is 'female' / 'woman' enough to get into changing rooms, why not elsewhere? And if sex is a social construct, and transwomen are female, there's no reason not to let them into rape crisis centres, women's prisons, women's toilets, women's open-plan changing rooms.
To reiterate that point, there is little to no acceptance among trans activists that trans women are male. This is argued against vehemently. Any attempt to create unisex facilities in some cases, and single-sex facilities in others, won't work because these people are claiming to be female and want access to female-only facilities.
