You three (four) (five) (six) bricks just don't (can't?) get it. It's not about what I think, it's about what we think, collectively. We live in a society governed by "We the People". Laws give order to our lives, and our society. Laws are implemented by imperfect human beings, you and me. Reality, fellas.
Did you see the bit on the 19th Amendment. You see how that worked? States gave women the right to vote, and hold office, long before they had the right, nationally, to vote. The feds followed suit.
This is how the republic was meant to work. The states are experiment stations which will adjust to the whims of the population of each state. The eventual result of these 50 experiment stations will be a national law, or a Constitutional Amendment, implemented on the basis of what has been shown to work, in the states, and what is socially acceptable, nationally, extrapolated from the states examples.
You dunces get caught up in, "Your this and I'm that". Your relatively dull individuals, and I'm not. Despite that fact, we still all should get a say. "Homos" and "lesbos" included.
