> But if this whole issue is because women are frightened of predatory men in that circumstance then this issue is with predatory men not with those that happen to be LBGTIQ+. The intersection is likely vanishingly small.
The issue, I would guess, is not necessarily with predatory men that are also LBGTIQ+ (which would be vanishingly small as you say), but perhaps with predatory men that would claim to be LBGTIQ+, which these predatory men would have an incentive to do. This could be a much larger segment of the population, relatively speaking. That said, this is not the point I was arguing, as I don't have a clearly defined opinion about this.
What I don't understand is why people think that leaving things as subjective as they are (and therefore more prone to prejudices) is better than having simple and clear definitions and legal rules that can be adapted to each person's personal circumstances (again, assuming that you do want to have separate bathrooms).
Especially given what you said in another comment:
> That 'at birth' thing is arbitrary if for example you are a mix of male and female cells, or as in the story, genetically one thing but partly physically another. Especially if it takes some time to work out what the facts are for a given person.
Exactly. Since it would be difficult to work out what the facts are, it would be better to have a legally binding document that clearly says "you are allowed to go to these bathrooms". Then you would no longer have to "work out" these issues every time someone makes a fuss.
Although, I will repeat again that you'd need to allow this document to change after birth, as that would be required in some cases.
