(Some) Jews flip back and forth between designating themselves as an ethnic group, religion and nationality, depending on which designation serves their purposes at the moment.
None of the three really fits all people who call themselves Jews.
It’s well-known many Jews don’t consider converts to be “real Jews.” And there are a great many people considered by themselves and others to be Jews who are open atheists. So religion doesn’t define who is a Jew, at least not in the same sense as it does being Catholic or Muslim.
Jews are obviously of a great many nationalities, so that doesn’t seem to work as an overall definition.
Ethnic group (the term race hasn’t worked since Hitler) doesn’t fit too well either, as it’s obvious by appearance that Jews incorporate many ethnic strains.
So what do you think is, or should be, the definition?
