Biological sex is binary, except in cases where it isn't.
It's my understanding that sex is binary, because the word binary refers to how many of each sex is required to reproduce. And that it must be one from each category. Otherwise, you know, it doesn't work.
I don't think throwing legitimate transwomen under the bus because of what a tiny minority of (using your words) nefarious fakers might do is the answer.
How can you expect people to consider you credible, when you spend all your posts claiming there is no such thing as a sex category that can be reliably defined, and in the next breath claim that you can define transwomen!!
On what possible basis??
We don't convict whole groups based upon what individuals within that group might do
Again, your slip is showing. Expecting men to use the facilities of their sex, isn't convicting them of anything.
And, of course we assess risk based on a class analysis. When I'm DBS checked, I don't go off alarming because I'm not a paedophile.
98% of all sexually violent crime is committed by men. The common denominator is that they are male. Not how they identify.
There are plenty of women who would be willing to segregate along the lines of men with gender dysphoria, versus fetishistic cross dressers/autogynephiles.
But as it's impossible for anyone to make a distinction, that can never happen. You can blame transactivists for this, not the women pointing it out.
