A contradiction in the liberal view of gender

[Losty]

I think you're confusing gender with gender role. It's not the same thing. Transexuals do not reject the gender roles that come with whatever anatomy they're born with, but rather they identify with a different gender.

A transwoman may love baking and sewing or she may love playing sports and being the sole breadwinner. Those are socially imposed gender roles that are arbitrary. Identifying as a certain gender has nothing to do with identifying with arbitrary gender roles.
