CMV: If you can identify as any gender, you can identify as any race

I don’t understand the logic of transgender people dismissing gender as a “social construct,” since other categories such as race, species, and country of origin are all based on social constructs regarding who is what race, what constitutes a separate species, and what borders determine a country. 

If we can merely disregard the correlation between sex and gender because gender is a “social construct,” why can’t someone disregard the correlation between genetics and race because race is a social construct?

For example, most black people have genetic ancestry  to Africans (including black people from the Caribbean). We say that if you have the physical features (dark skin, facial features) associated with African ancestry, you’re black. But what if a black person feels like they are more aligned with the customs and culture of white people? After all, race is just a construct, so why can’t he just identify as white, and demand all people recognize him as white or else it’s hate speech for not acknowledging who he “really is?”

I think your confusion is a result of a misunderstanding about what transgender people mean when we say that gender is a social construct. We don't mean that gender doesn't exist, we mean that gender norms are made up and don't need to be adhered to - for example, you can identify as male and wear dresses, and that doesn't make you any less male because the idea that only women wear dresses is a social construct. Gender as a part of our biology is very real though. Gender and sex are both real and both biological, the difference between them being that sex is determined by your body and gender is determined by your brain. Studies have shown that the brains of trans men have a more similar structure to those of cis men than those of cis women. Similarly, trans women have the same brain structure as cis women. If you are born with a body and a brain that don't match, so that your gender and sex don't 'match', then you are transgender. It is biological and real and not made up. Identifying as a race for which you have no genetic or familial connection, on the other hand, has no basis in biology and therefore doesn't make sense. So it is not fair to compare that idea with being transgender.

That being said, there actually are times where a person could be seen as trans-racial and it makes sense. An albino person from a black family, for example, may be white passing but still consider black culture to be a strong part of their identity.
