What exactly is "genetic Israel"? Does is include anyone with Semitic blood? Anyone with a single Jewish ancestor? Are the Catholics of Spain, 20% of whom have Sephardic blood, part of "genetic Israel"? What about those converts to Judaism who have no genetic ties to Israel? What about the vast number of Eastern European Jews who have no genetic linkage to the Holy Land? What about the large number of middle eastern Muslims who have Jewish ancestry?

Now post some goofy picture to show your level of intellect when confronted with a confounding concept. Or better yet, just redecorate the forum again with wild colors, fonts and images that "pop. I have a gay cousin who redecorates too when ever he gets stressed or flustered as a way of demonstrating his control over his environment.
Ask the RC I borrowed the term from.
