Is it still a moral choice on your part if someone puts a gun to your head and says "or else"? Not in any ones world but your twisted little fantasy world.
Now in the world of Libertarianism where morals are not set and change from one person to the next, and refuse to think about the greater societal good only their wants (example the drug issue) who knows how long it would take for the society to get to that point. At some point in the future it could lead that far down the path to anarchy. That is until society has gone to far and a police state must step in to protect the weaker and emplace morals again.
Without our Christian founders we would not be enjoying freedoms and be such a unique country in this world. When we loose our Christian foundations and morals we will loose our freedoms as for-told by our founding fathers.
