You have to be very naive and sheltered to not see where self-ID will end up.
It won't be a question of "a tiny minority" of men identifying as transwoman to nefariously access women's spaces. It will be every sexual predator that can get away with it, anyone who decides to troll for a laugh, and anyone who wants to take advantage of the space.
And then because of that, you will get husbands, fathers and brothers demanding access to women's facilities in order to protect their wives and daughters while they use the facilities.
In order to keep the situation under control, you'll end up with security guards in women's toilets and changing rooms in shopping centres, for example.
And this is what happens with unisex facilities. The unisex toilets at Fabric back in the day were monitored by security guards inside the toilets who funnelled biological sex to one end or the other, and hurried you in and out because there had been so much trouble in them.
Likewise, other fashionable toilets in trendy restaurants suffered the same problems. It's not just about voyeurism, but people using them to have sex as well.
And that's just toilets. Changing rooms, hospital wards, prisons, refuges are another kettle of fish entirely. Even HCPs and border guards are yet another issue again. Would Flora be okay with a self-ID TW border guard carrying out an intimate search on her at an airport? Does she not see that the vast majority of women would have a serious issue with that?
The practical application of this ideology in the real world would lead to consistent instances of public unrest and disorder. A law such as self-ID would fundamentally create consequences that would undermine and fracture the State. That Flora cannot apparently see this, as a 29 year old from an educated background with a mother in government, is frankly ludicrous.
