I don't think they addressed the issue specifically, but I'm pretty sure that the Founding Fathers probably would have had a few choice words for governmental enforcement of moral views.
I'm not saying I agree with Pornography, but what it boils down to is I don't believe we can enforce laws banning it, but it IS our responsibility to point out what's wrong with it, and hope people listen.
New evidence shows porns kicks off a chemical addition (pleasure center in the brain, like heroin)linked to behaviorial changes...antisocial, addictive behavior.
I'll look for the news item again.
That has to be the most over-used fallacy in political debate. "You can't legislate morality!" What hogwash! Legislation is the codified morality of the people! Why is killing illegal? Because the people have deemed that it is morally reprehensible. Why is theft illegal? Because the people find it morally wrong.
Even the idea that everything is OK if you don't harm somebody else is based on the moral foundation that harming someone else is wrong!
What people really mean is: I'm uncomfortable with that level of morality, so leave me out of it.
