I know lots of clergy who say they do not speak up publicly for marriage equality, yet support it privately. They say they want to minister to all of their congregation no matter what their political beliefs. They say the people who are fighting marriage equality are kind and wonderful people who are hurt when confronted on their homophobia. They say to make people uncomfortable in their prejudice is itself a kind of intolerance. And, I have little doubt, had these clergy served two hundred years ago, they would have used the same excuses not to address slavery.
