Silverman may think of herself as edgy and new, but she is actually a stereotype herself -- the non-Jewish Jew who substitutes liberal politics for religion. For at least a century, large numbers of nominally Jewish Americans have demonstrated far more attachment to liberal politics than to actual Judaism. They declare that Judaism demands social justice, equality, gun control, liberal abortion laws, and an increase in the capital gains tax and they adhere to these tenets, well, religiously. Columnist and radio personality Dennis Prager likes to say that Jews are the most religious people in America -- but their religion is not Judaism. (This does not include observant Jews.)
Judaism does command social justice of course -- just start with the prophets. But normative Judaism is not the Democratic Party at prayer. Abortion, for example, is traditionally forbidden except to save the life of the mother. The Ten Commandments take a dim view of open marriage. Capital punishment is sanctioned for some crimes. And above all, Judaism demands that human beings worship God, not themselves.
It's a free country and secular Jews can believe and say whatever they like. But it is tiresome as well as false for them to parade their liberalism as the authentic expression of a great faith.
