jewish genetics are a meme. they have changed the rules on jewish genetics so many times through history that now there are black jews, polish/ukranian jews, arab jews, and ginger jews. it's the cultural beliefs they pass down that are the problem. 99% of people raised in a jewish household to believe they are jewish will turn out just as bad as a "pure-blood" jews. that's why shabbos goy are so dangerous.
