As a Libertarian I believe that marriage is between the partners, not the state. The State interest in Marriage is the support of children produced in sexual union. There is no compelling state interest in Gay marriage. Further with genetic testing, there is no state interest in marriage at all. Test the children and publish the identities of their parents (except in legal adoption). If the state forces Christians, Jews and Islamist to accept as marriage something they consider an abomination. These groups should join and vote to remove marriage from a state the abhors faith, and return it to the faith based institutions where it belongs.
