I'm your hard pressed example that has never given money to a church.
I also support true equality: the complete removal of any government involvement in marriage. All consenting adults should be able to get married without any government permission or regulation. No future group of persons should have to ask the government for permission to exercise the rights that do not belong to the government to begin with. If the government believes it gives you such rights, some future politician will find it all too easy to believe they have a right to revoke them.
