Remove marriage from government control. Replace current system of marriage with civil union, identical to the current state with all benefits, tax, inheritance, etc. Allow gay civil union. Marriage is now a personal contract that someone makes with God, their church, their rabbi, their internet ordained friend (hey that's me!) etc.
Now, people can no longer argue over the sanctity of marriage. If they want to combat gay civil union, they have to do so under the banner of "I just don't like gays"
