What truly threatens society are laws that criminalize the actions of peacefully, civilly TELLING THEM TO GO SOMEWHERE ELSE. Personally, I think a presidential candidate who campaigned on a platform of de-criminalizing bakeries, landlords, employers, adoption agencies, military agencies, schools, etc. who choose to peacefully, civilly tell open homosexuals to take it somewhere else, would WIN.
Again, the problem isn't lack of laws criminalizing private/personal sins and weaknesses (as opposed to public sins such as murder, thievery, rape, assault, etc.). The problem is the existence of laws, pushed by the left, that criminalize moral people who peacefully, civilly tell homosexuals to go somewhere else.
I think we're in agreement. Adultery and homosexuality are obviously undesirable socially, I just don't think that having laws (especially federal laws) against private vice is the right way to deal with them.
That being said, I often wonder why the "family values" crowd obsesses so much over homosexuality as the biggest threat to families, as opposed to divorce or adultery. Most families aren't being broken up because mom or dad decide to go gay (and in fact, there would be no such cases if there weren't a social pressure for homos to be closet cases). They break up because of no-fault divorce laws and a society that finds adultery acceptable (much more so than homosexuality)
