What ramification these consensual behaviours have on the rest of society, (to wit, those who give no consent) is not being talked about here. Do what you will in your home, with consenting adults, but: MY insurance costs go up as people get sick from their indulgences. MY medical care system is compromised as tainted blood enters the blood banks. MY marriage will be cheapened by the removal of the last real stumbling blocks to even one jurisdiction granting license to these ersatz unions and the granting of "gay marriage licenses" full faith and credit under the Constitution. And my wife and I will be expected to shoulder not only the tax burden for those who are sick, but pay their 'spouses' insurance and survivor benefits. I do not consent.
Besides, making an issue of supposed gay marriage, which is at the root of this issue, grants a veil of apparent legitimacy to an incredibly promiscuous lifestyle.
After all, this has diddley squat to do with rights to perform sex acts in the privacy of one's home. Anyone discreet can already do that.
This is just appears to be a small but integral portion of an overall agenda to legitimize and license perversion, then get the rest of us to pick up the tab.
