Jew weighing in here, brought in by Baseball Bugs... Judaism is not a "race", it can be considered an ethnicity. My race is Caucasian. As far as what to make of Elvis' Jewish ancestry, which I was not aware of until Bugs brought it up to me, I'm not sure how much to make of it. To me, religion is mostly about how you identify, not this silly rule about which parent passes it down. IIRC, Catholicism (or is it Christianity as a whole?) passes it down through the paternal line, so a kid with a Jewish mother and Christian (or Catholic) father is kinda stuck there in terms of which wins out, by that argument. –
