However, parents have never been perfect and I don't think it is anything new, so there must be another set influences which deserve credit for the modern shape of morality.
Personally, I would rather have Billy Graham as my example instead of Larry Flynt.

I agree that the was a sea change, caused by communist leanings, in '64, but that the tide went completely out with Roe vs. Wade. The very promise of the premise of the Preamble ~ Life, Liberty, Pursuit of Happiness ~ the first premise shat upon. Three things, how hard is that? Regardless, Life is compromised, Liberty has been traded for security, and the pursuit of happiness determined by the righteous.
