Who said anything about public?
Anyway...
If you are a butcher, you can sacrifice animals as much as you like in public, which goes to show how screwed up our country is that they allow an animal to be unnecessarily sacrificed for food, but not for religious beliefs...
America is a weird country. People give more love to their pets than their family, then they go eat brutally slaughtered roasted dead animal flesh at McDonald's...
When it comes to sex, we have laws on the books about public obscenity, and indecent exposure. This has nothing at all to do with the right of gays or straights to marry and have sex any way they like in the privacy of their own home...
"How can a Court allow same sex marriage but then uphold laws prohibiting incestuous marriage?"
The only reasonable argument against incestuous marriage would be genetic dangers if children were the offspring.
Do you remember when it was required by law to get a blood test to get married?
That isn't an issue any more.
If both parties are consenting adults, I don't see a problem.
(If people take the Bible literally, then from Adam and Eve the direct descendants of Adam and Eve were incestuous to produce further human beings. Who did Adam and Eve's children procreate with but either their brother or sister, or with their mom and dad?)
I have addressed the question of tax laws previously were a man to marry his adult daughter to avoid the estate tax, and the scientific reasons that would have to do with the danger to offspring of inbreeding are valid concerns, so excluding those issues, tell me what is wrong with informed and consenting adults marrying?
If you look to the history of this country, like or not, we have seen the taboos change over time. It used to be taboo to do certain things which are now so routine that people don't even pay attention...

Quote from Pa(b)st Prime:
Race and gender are protected because they're not elective. Religion and sexual orientation are choices.
If you think religious freedom is boundless than see how far you get with a public display of Devil worship or animal sacrifice.
You've refused to answer this before. How can a Court allow same sex marriage but then uphold laws prohibiting incestuous marriage?
