Ballots are created by governmental departments after freedom of choice is challenged by those wanting Law to be passed for their own needs of belief. Gay marriage is personal and not government challenged. This is a moral issue to live and act upon on a personal basis not the government. Leave religion out of this, as it is self explanatory by earth's natural existence that male and female be the only form of reproduction.
The animal kingdom does not document mating with one another. Why should humans? Because human documentation is necessary for geneology purposes, thus demands organization of a family tree. Bottom line....organizating the human race, border of lands, time segments, body of waters, air space, taxes, finances, disease and everthing else in between.
Why make it public or force the law to make decisions on two human beings of same sex wanting to have sex? It's punishment enough to exist with subnormal genes. I think this raucous is irrelevant to the normal but disturbing to those who do not have the problem and who rather it go away.
