When you talk about they stock market you know it is an invention by humans. Same with things like nationality, or ideologies etc.

Race has this veil of credibility. People think it is an actually scientific term rooted in biology. People think you can look at someones DNA and see if they are black/white/Asian. You can not! It is not a scientific term. There is no biological way to separate people into races. It is a social construct that acts like it is not.

What race someone is literally depends on what people think. There's no scientific way to establish the race of someone. A popular example is that Italians and Irish were not considered white.

Idk how you can't follow my argument, it's clearly about the fact that it's not definitive whether Jews are a race or not. It is definitive that they are an ethnic group because you can establish that via culture and heritage and language and obviously, religion.

I think Indians and Taiwanese look very different and don't have a similar origin, but people would say they're both "Asians" by race.
