Incredible statement, and you contradict yourself later on in your response. If I go put on a skirt that does not change my gender. You are, perhaps intentionally, injecting commentary on differing cultural norms on gender expression in order to deflect from prior statements that are more definitive on the malleability of gender itself. There's that motte and bailey, again.

>For some cultures, genitals have little to no bearing on one's social expectations. Fit into the role that feels right, who cares about what is in your DNA

This is fantasy, but I'll play a long for a minute. If one's physical characteristics have little to no bearing on one's social expectations [for gender], then why is it necessary to implement significant physical alterations via medications and surgery to "fit" into a role that feels right?
