I don’t personally disagree with you and I think gay marriage is totally ridiculous. However since government in our real world does get involved in these things it should be up to each individual state as to who they issue a marriage license to for civil marriages.
States have no right to issue anything except licenses between one man and one woman. Anything beyond that is a breach of their rightful authority.
William Blackstone:
“Good and wise men, in all ages...have supposed, that the deity, from the relations, we stand in, to himself and to each other, has constituted an eternal and immutable law, which is, indispensably, obligatory upon all mankind, prior to any human institution whatever...This is what is called the law of nature, which, being coeval with mankind, and dictated by God himself, is, of course superior in obligation to any other. It is binding over all the globe, in all countries at all times. No human laws are of any validity, if contrary to this; and such of them as are valid, derive all their authority, mediately or immediately, from this original.”
Alexander Hamilton:
“Upon this law, depend the natural rights of mankind, the supreme being gave existence to man, together with the means of preserving and beautifying that existence. He endowed him with rational faculties, by the help of which, to discern and pursue such things, as were consistent with his duty and interest, and invested him with an inviolable right to personal liberty and personal safety.
“Hence, in a state of nature, no man has any moral power to deprive another of his life, limbs, property, or liberty; nor the least authority to command, or exact obedience from him....
“Hence also, the origin of all civil government, justly established, must be a voluntary compact, between the rulers and the ruled; and must be liable to such limitations, as are necessary for the security of the absolute rights of the latter; for what original title can any man or set of men have, to govern others, except their own consent? To usurp dominion over a people, in their own despite, or to grasp at more extensive power than they are willing to entrust, is to violate that law of nature, which gives every man the right to his personal liberty; and can, therefore, confer no obligation to obedience.”
“When human laws contradict or discountenance the means, which are necessary to preserve the essential rights of any society, they defeat the proper end of all laws, and so become null and void.”
