Quote from Cutten:
I didn't disagree with 1. However I would point out that many people think that trying to indoctrinate a child into religious thought, and forcing them to attend church services etc is highly undesireable. So your "save the kids" argument could theoretically be used as a reason to take your kids away and give them an education where they are taught about *all* points of view regarding religion and other moral matters.
2 is an acceptable reason for regulating conduct in *public*. What happens behind closed doors does not affect your family's safety at all.
In addition, you say "constitutional of course". The Constitution merely elucidates already-existing natural rights to life, liberty, and the pursuit of happiness. By definition this means that if someone is not infringing anyone's rights to life, liberty, and the pursuit of happiness (which selling sex on private property does not do), then they have a natural right to indulge in any behaviour they choose. Note that the Constitution does not mention a right to regulate other people's behaviour because you don't like it, or because it offends your sensibilities, or because it is unpopular.
Your position, as stated above, could be used to justify preventing streetwalking, sex in public on the street in front of your home, and so on. It cannot justify infringing on sexual relations in private, unless someone is harmed against their will during the act (e.g. child pornography).
