Show me some credible developmental process of genetics, neurology or hormones that makes you think you're a turtle AND demonstrate that there's no treatment that will return you to awareness that you're a human being, and THEN show me that you can have some hormone treatments and surgery and live out your life happily and without further maladjustment as a turtle, and sure, I'll drive you to the vet myself. That's the case with transgender and intersex, so I think that's a fair yardstick.
