I recently watched a comedian on YouTube trying to sort out what it is exactly that
makes a Jew a Jew. Having only minimal familiarity with the Old Testament, and
possessing almost no knowledge of modern Talmudic Judaism, the poor man was
entirely at sea, and eager for somebody to explain it to him.
I don’t blame him. The term is used multiple ways by different groups with different things in mind.
Sorting out the various claims to Jewishness is not easy, and I think it’s
fair to say the vast majority of modern users of the term either get it wrong
or use it in such an ambiguous and inconsistent way that nobody really knows what
they are talking about.
The biggest contributors to this confusion, oddly enough, are a certain subset of … er … Jews.
