I mean, race is a human construct anyway. We’re all human. We can all fuck and reproduce viable offspring. We’re all the same species, and the difference in our looks was historically driven by geographic separation which resulted in different “looks” based on locality. We don’t have that geographic separation anymore and its only a few more hundred years before we all generally look alike, worldwide.

I think it has more to do with that tricky thing about the Jewish faith where it doesn’t matter if you believe in Judaism or not, if your mother was Jewish, you’re considered “Jewish” no matter your rejection of the faith. I remember a David Cross bit about it.

From an empirical standpoint, the concept of “race” can be useful sometimes, like black people have higher rates of Sickle Cell (and being treated poorly by ignorant people of many other races, regardless of class and other factors), while white people have higher rates of Cystic Fibrosis (and in most of the Western world, a higher rate of acting entitled).

Jewish people are not technically a race bc anyone at all can become a Jew by conversion, but as a whole they do often tend to intermarry (or used to in the past?), which does lead to some traits being shared in common, especially visible when combined with similar cultural choices to look or act or sound a certain way.

So you are right, but… I’m not certain that all instances of the opposite line of thinking is entirely wrong either, especially depending on how it is used.
