The gov. can't help but legislate morality there is no way around it.
That being the case your argument collapses.
I think you need to define your meaning of "morality" and "personal behavior" here. (ATB)
I think Andy has a point. I was referring to the attempt to control individual behavior that is properly part of the personal sphere. It does not include the obvious morality-based "you can't hurt, kill or rob anyone else" type laws.
