Proof

When I want to illustrate a prime example of how transgender people are born and not self made, I think about Abby Stein.

Imagine growing up without television or internet in a deeply religious orthodox Jewish sect which would have left you completely devoid of outside influence. Then one day by sheer happenstance, you get access to the internet and discover there are others like you; others who knew to their core since young that something was up with their gender identity.

Abby eventually left her sect and transitioned but she is the perfect laboratory experiment if you are seeking proof that transgender people are very much the real deal.

She and David Reimer are, for differing reasons, the cases I think about most.
