Jews and Israel are not vague at all. Real Jews are descendants of Judah. Israel is just a middle eastern country where some of them live. The Israelites are all the descendants of Jacob, including the Jews. Hebrews are the descendants of Abraham, which includes the Israelites and billions of other people.

Israel is only a modern country containing a minority of real Jews. Jews claim the word anti-Semitism as only applying to them, when it actually and technically should apply to all descendants of Shem. By Y-DNA, I'm a descendant of Shem, so I'm at least a tiny bit Semitic, as are many people who have German ancestors.

Jew and Israel are neither equal to the Israelites of the Bible, so there is no logical reason to be forced to like either one of them on religious grounds. Based on historical actions, I have good reason to not like either one.
