According to Jewish law, if his mother was Jewish, then so was he. The concept of a "half-jew" is modern invention, and not accepted by orthodox Jews

I know, I'm not talking about half-jews at all; if I make up a religion stating lizard aliens identify their descendants with the name Leonardo, does that make him a lizard alien? According to me, yes, but that doesn't change at all who he was.
