Funny that people who don't believe scientific facts will believe in Global Warming and 72 skanky virgins.Science is science and DNA tests prove that Jews have a common gene that traces them back to Moses and Aaron's time."nevertheless, many people find it difficult to accept the ideas that judaism is not hereditary, but a religion, and that jews who abandon the jewish faith, whether they adopt another religion or none at all, are no longer jews."
that may be a conclusion that a biologist draws, but it does not determine the position of normative jewish law.
so ?...science is science.it can not just be trumped by normative jewish law
