According to the American census, a person is Jewish if they practice the Jewish religion. Which means there are far fewer Jews in the US than is usually recognized. They are not counted as an ethnic group separate from "Caucasian". Nor are Arabs, for that matter.

Can we just separate the religion from the political ideology, please? It's not an ethnic or cultural group either. Israeli Jews are not considered "Israeli citizens" by the government of Israel; they are considered "Jewish citizens". And so is every other "Jew" (definition not given) in the world, even if they are not citizens of the state of Israel and have no intention of ever going there.

They're so good at confusing the issue so that they can hide under the radar.
