I "insinuated" something I said "outright"? Where?
You're the one that insinuated that I started this because "my guy lost". No assumptions there... you said it outright.
The Marshall court says different.
You can repeat what you wish all you want. The Constitution is pretty plainly written. You'll find next to nothing in that document suggesting what you are asserting. The Federalist Papers were pretty thorough in their discussions on the matter as well.
There is NO mention of marriage in the Constitution. Following that document means that the federal government has no basis for making any ruling on the institution of marriage until there is an amendment saying otherwise (which would be contrary to its original underpinnings). It can aid in rulings regarding domestic contract disputes but nothing more. It simply is not allowed (not that it's stopped all kinds of impropriety)
That's akin to saying "There's no mention of planes in the constitution so we shouldn't use them in defense of the country".
