"Wherever the real power in a Government lies, there is the danger of oppression. In our Governments, the real power lies in the majority of the Community, and the invasion of private rights is chiefly to be apprehended, not from the acts of Government contrary to the sense of its constituents, but from acts in which the Government is the mere instrument of the major number of the constituents."
The idea that the rights of a minority group - and certainly homosexuals are a minority in our society - should have their lives dictated by the fetishism of the masses goes directly against what Madison saw as a critical responsibility of government. Gays do not ask for benevolence, only equal treatment under the law. Equality is not charity.
"Justice is the end of Government. It is the end of civil society. It ever has been, and ever will be pursued, until it be obtained, or until liberty be lost in the pursuit."
