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.
