I don’t think enough attention is given to the three key axioms — typically unstated — of advocates for gender fluidity and gender choice: 

1. A person is (essentially) a mind that happens (accidentally) to inhabit a body; 
2. That mind rightfully has absolute power over its body — that is, in relation to the mind the body has no rights; 
3. Remedies for what the mind believes to be the deficiencies of the body are purchasable in the marketplace. 

In short, the whole movement is built on a kind of gnostic capitalism. 

UPDATE: This essay in The Tablet is an excellent reminder of how much money is to be made from promoting the above model of gender and sex. It would be helpful if our cultural critics would become just a little more skeptical about advocates for anything whose success in advocacy would line their pockets. And those who rail against the big tech companies should remember that that category includes biomedical tech.
