Interestingly enough, the vast majority of people that I have talked to that call themselves libertarians DON'T partake or believe in the sins that you've just described. However, they have no problem with OTHERS doing it. Hence the following description of your "religion":
"Those who embrace libertarianism believe that there is no ultimate authority to which men and their civil society must answer other than themselves and the words of their own constitutions and laws. Men are "free," and there should be as few restrictions on "freedom" as possible."
The problem with libertarianism FBD is that their is no mention or acknowledgement of God in their beliefs (Misguided Christian libertarians are another story).
While the following words were written specifically to deal with homosexuality, it fits the libertarian social agenda as well:
"For Christians, it can’t be surprising that gay culture’s deformities and vices go so far beyond homosexuality itself. While we understand homosexuality to be innately wrong, we also understand that the bigger problem is people rejecting God’s standard, and thus God Himself. Once that happens, the door is wide open to any sort of behavior. As Dostoyevsky wrote, if there is no God, everything is permissible."
Be it libertarian social policies or their "free trade" policies; without God everything (and anything) is permissible.
I highly doubt you'll hear a Demcocrat says those word.
