There's no such thing as "Transracial"

[sub.theory]

102. So, you are saying it's so....because you say it's so

You fail to show that a person who self identifies as black is not actually black. You are simply claiming it's so, but there is not a scrap of actual evidence you are using to support that. You have decreed that she is not actually black, because you have decided she's not black. How do you have any idea what her "real self" is? Are you her? You have, correctly, acknowledged that racial identity has no genetic meaning (and thus is not objectively real). Your logic, however, at determining that gender identity is not genetic and thus not objectively real has no scientific basis. There are chromosomal differences that mandate gender physiology. The very hormonal levels that you dismiss are indeed very real on the biological level. No biologist or physician would ever claim that regulation of hormone levels is not biologically significant. In fact, disease is often the result of abnormal levels.

So, again, why is race a fixed construct but not gender?

Edit: My point is that you can't say that gender identity is a construct, when it has clear genetic basis, but say that race identity is fixed when it has no genetic basis.
