An interesting post by Bruce Adelstein on the Three Jews blog, focusing on “when Jews” — presumably observant Jews — “should support or oppose an American law of general applicability that is not in accordance with halacha.” His conclusion: “[W]e do not base free speech law on [Jewish legal principles], and we do not even base opposite-sex marriage law on the halachic definition of marriage. We should not oppose civil same-sex marriage merely because it differs from halacha.”
