A limited government of enumerated powers that recognizes the citizen as sovereign is the foundational philosophy of these United States and what set it apart from every form of government that came previously.
That you think such things are simply allowance for licentiousness shows that you don't respect the foundational philosophy of these United States and are more ideologically aligned with those forms of government that think ‘righteousness’, however they chose to define it, is more important that recognition of natural rights and freedom of conscience.
That's why all those Founders thought religion was unnecessary, right?
Sorry Charlie, you don't get to move on to eating the cream filling of the next oreo until you finish the whole cookie from the first one.
