From a year ago:

That’s like doctors offering a seminar for other doctors on “Understanding the immortal soul: answers for physicians.” There is no immortal soul, and there is no “gender identity” either – not in the sense of being a real, tangible thing that doctors can research and understand. There are feelings people have about their sex and “gender” but that’s more a social and/or psychological and/or emotional category than a medical one.

It’s all very phlogiston.
