I don't know. But to be honest this here is one of the things that I don't like about this subject... It's consuming so much time, my time here typing to you and society's time as a whole. That time could be used for more productive things, such as scientific & technological advances that help society, rather than appeasing the delusions of a few people with chemical imbalances.

Maybe the correct answer is to give these trans people the operations they seek so that they are far less likely to ever reproduce -- I'm guessing post-op MtF trans can't reproduce? -- and this genetic anomaly is bred out in a couple of generations so that we can get back to normal.
