Let me clarify, I'm defining morality as a choice. As if the two words are synonymous, which I believe they are.
I'm talking about morality in it's most basic sense, deciding what's right and what's wrong. When the government makes a law and enforces it, they are saying something is, in essence, "wrong," and backing it up with a punishment. Many people try to say that people's personal morality and bias should stay out of our government, but I believe that's impossible, a person's worldview will always affect the choices they make in regards to government...
(Also, I do believe that our nation was founded on "biblical" morality, and without that you do have "The makings of a disaster.")
