A. Who cares what marriage has been historically. It's a part of government benefit distribution. It is subject to change just as any other part of government is. Appeal to tradition is dumb.

B. The fact that there are other views besides the Judeo-Christian living in the US means that enforcing the mainstream christian view of marriage on others is religious intolerance.

Religion should stick to social welfare or get out of my country, because I want the government out of my life.
