You are correct, markomalley. One cannot rationally support a constitutional right to homosexual sodomy without also supporting a right to incest, polygamy, polyandry, and pretty much whatever else consenting adults want to do. Scalia and others pretty much wrote as much when they dissented in Lawrence v. Texas.
Scalia: “State laws against bigamy, same-sex marriage, adult incest, prostitution, masturbation, adultery, fornication, bestiality, and obscenity are likewise sustainable only in light of Bowers’ validation of laws based on moral choices. Every single one of these laws is called into question by today’s decision dissent.”
Without our country’s Judeo-Christian foundation, there is literally no limit to the depravity that man will do. Want to know what Lot felt like in Sodom? Prepare yourself, because that is coming, my FRiend.
You just had to throw in Lot, didn’t ya?
Genesis 19:30-38
Interesting example you brought up, now for the rest of the story:
Both of Lot's daughters got Lot drunk and had sex with him, both resulting in pregnancies.
