Congress passed the Morrill Anti-Bigamy Act and President Lincoln signed it into law in 1862. You know, that Republican President who fought against the twin barbarisms of polygamy & slavery? Funny how polygamy is a barbaric institution, yet homosexual unions are “enlightened.”
Reynolds v. US upheld The Anti-Bigamy Act in 1879. To achieve statehood, Utah was forced to denounce polygamy. So, it’s safe to say that both Congress and the US Supreme Court have a history of supporting one-man/one woman marriage.
Of course the people of the states have the right to regulate marriage, so long as they exist within this parameter (eg. common-law marriages, age restrictions, consanguinous marriage between cousins). But to declare that there should be no federal, state or any governmental promotion of one-man/one-woman marriage is ahistorical and not part of American legal tradition.
You said that very well, I'm going to try and remember some of that language.
