Once again, you are making the wrong argument, in the wrong place, at the wrong time.
These are arguments that should be made, that have been made, to a legislative body. In California, these arguments convinced the legislative body known as the People, and they passed a law against allowing two people of the same sex to pretend to be married.
The California Supreme Court is not equipped to sift facts and arguments, integrate them with public opinion, and then to pass laws. That's not their job, and in fact the California Constitution specifically forbids them from doing so.
Therefore, the burning issue of the moment is not the compatibility of various body parts, nor the continuation of the species.
The issue at hand is the usurpation of the right of the People to legislate on matters that are within their competence. The prerogative claimed by the California Supreme Court, and by the SJC in Massachusetts before it, is the power to bind us, in all cases whatsoever, which leads back to Paine:
"Tyranny, like hell, is not easily conquered; yet we have this consolation with us, that the harder the conflict, the more glorious the triumph. What we obtain too cheap, we esteem too lightly: it is dearness only that gives every thing its value. Heaven knows how to put a proper price upon its goods; and it would be strange indeed if so celestial an article as FREEDOM should not be highly rated. Britain, with an army to enforce her tyranny, has declared that she has a right (not only to TAX) but "to BIND us in ALL CASES WHATSOEVER," and if being bound in that manner, is not slavery, then is there not such a thing as slavery upon earth."
I fully agree. The court had zero constitutional authority to hand down this ruling. I was just expounding on some of the other arguments involved.
