There are some people whose chromosomes don’t match their body parts, but it’s very rare, and has nothing to do with delusional people’s feelings.
Absolutely right. And even those people have either male or female chromosomes; they don’t have both.
Good doctors try to help people whose body parts are different from their chromosomes to have parts that do match. It may not be as easy as making them what their body parts indicate, but it makes them normal. Normal is still a concept of reason, logic and truth.
