You can’t get rid of race just by pointing out that it’s a social construct. There is a difference between a social construct and a delusion. Money is a social construct, but there is nothing delusional about acknowledging that certain rectangular pieces of green paper are more important to us than others. However, social constructs can only survive if there is something physical that enables us to perceive the distinctions that make them possible. If you cannot tell the difference between a one dollar bill and a five dollar bill by looking at it, paper money cannot survive as a social construct. Race survives as a social construct only because we have certain circuitry in our brain that enables us to draw these fundamentally irrational lines, based on a cluster of loosely associated properties.

However, once those properties failed to cluster together, the concept of race will fail to work as a social construct. As different races interact more and more socially, intermarriage will be inevitable, which will eventually lead to more people who look like you. Without racial prejudices to inhibit this process, the inevitable result will be that no one possesses enough of these characteristics to place them in a specific racial category. Everyone will be a little bit black and a little bit white, and no one will be definitely one or the other. This will happen culturally as well as physically, as even pasty-white people will be naturally inspired to embrace all aspects of what were formerly seen as non-white cultures.

Unfortunately, a lot of people who see themselves as anti-racist try to fight this process by protesting against so-called “cultural appropriation” and “Blackfishing”.

We can sympathize with the emotional reactions that POC have to these activities, and still recognize that they are actually the cure for racism, not a symptom of it.
