AZMike, we're probably not going to get anywhere with this discussion, but it's interesting and I'm having fun arguing with you.
I'd never heard of Natural Law before, so I looked it up. In a nutshell, it seems vague at best. I have to agree with ThomasJefferson, the only natural law when it comes to human behavior is best described by Machiavelli. Morality is what keeps us above that muck.
Sexual slavery and debt was real, it was not just POWs that were slaves. Look at wikipedia under the bible and slavery to find a real great quote about selling your daughter as a slave. Comparing criminal incarceration with sexual slavery is not a reasonable comparison. The comment about keeping kosher was really just to point out that many religious leaders, over thousands of years, have been interpreting the rules and stories in the bible.
To answer some of your questions: The behavior is wrong if it's a choice. Just like being stupid is wrong if it's a choice. But what about a scout with Downs? It's not a choice for such a kid. Let me ask you this, do you think gays choose to have same sex attraction? Do you think a gay kid can encourage a straight kid to become gay? If so, then that's where our differences are and there's nothing left to say.
I can understand that some parents will be uncomfortable with gay kids in other troops. Unfortunately the same thing was said of blacks until 1975 when summer camps were finally desegregated in the South. Do you think a gay kid is likely to abuse another kid more than, say, kids with Aspergers, or PTSD (both of which I have in my troop)? Sure, different kids need to be watched differently, but there seems to be no evidence that gay kids are going to be any more dangerous to other kids than kids with other challenges that we already have in our troops. Is it that you don't want gay pride meetings in your troop? Trust me, nobody else wants that either.
"Every kid may come from God, but so do all bullies, racists, alcoholics, and drug addicts. We are allowed to discourage that kind of behavior as well." In all of these instances the kid chooses to do these things. It keeps getting back to choice. Character and morality come from the choices one makes. For a kid that can't make that choice, and isn't harming anyone else, I don't see a problem.
