CMV: if gender is a social construct, people would be able to be "transracial"

This has been popping in my head for a while and I just can't think of a good counter argument, but it doesn't seem like I can be right. I mean if gender is a social construct, it is set up similar to race, and I think a transgender person would be treated as similar to their desired gender as a "transracial" person would be treated as their desired race according to this alternate reality. But again, this viewpoint just sounds wrong, so I've turned here for a good ol counterargument. My guess is I will be completely proven wrong. Bring it on.

Something being a social construct doesn't mean that there isn't also some amount of objective reality behind it. The classic example is the color green. There is no such thing as "green" from a physics perspective. Light is a spectrum and how we divide it is entirely a social construct. However at the same time there are a definite set of wavelengths of light that most people can identify as green. It's a social construct with some physics behind it.

With gender, it's a social construct but one that also has some biology and hormones behind it. There's some research suggesting that trans people tend to have brains more similar to their target gender than their birth sex and that trans women often have a gene that reduces the ability to absorb testosterone leading to feminization. It's quite possible that some trans people have a brain that is one sex in a body that's a different sex and that this mismatch is what causes a lot of symptoms. 

Meanwhile for race, we have absolutely no evidence that race has any mental effects. Which means it's pretty impossible to have a brain of one race and a body of another. It doesn't mean that people can't be socialized as races different from their body, but there isn't a biological basis for the disconnect.
