Marriage, as a civil institution, is not now, nor has it ever been about who the partners in the union are having sex with, or not.

The civil institution of marriage is about certain benefits and entitlements that are extended only to those whose relationship is legally recognized by the state.

Does anyone here understand that? This isn't about sex, it is about health insurance, legal rights involving guardianship of children, and of entitlement to benefits provided by the state, like the tax benefits for married couples.

This controversy isn't about sex, and who is having it with whom, or in what ways it is being done.

See? Not about sex.
