They really want to have it both ways. If he says he identifies as female what right do we have to deny it? If they say he is lying about identifying as a female then anyone identifying as a female can be called a liar. We are at the point of it being a matter of how much indignation is shown by the identifyee when accused of lying. I hate that there is even a debate about the subject but I think he should walk because of equal protection under the law. He has as much right to identify as female as any other person has to identify as female. We have to close the circle now.
This is why trying to rewire nature is a doomed enterprise, because doing so takes you into dead-end paths which nature worked around successfully millions of years ago.
We are as we are for very, very good reasons. There is a lot of undoing to do, to get back to ourselves.
