This is an interesting distinction. A lot of lefties believe that anything referred to as "morality" is no different from religion.
Of course, quite a few of us who believe in God, believe the same thing. i.e.: morality comes from following God's law.
But the secular law can and should treat them as separate concepts. "Thou shalt not steal" is unambiguously a moral concept, whether you believe it comes from God or not.
I guess I don't have a point. Just making an observation that has some bearing on the fight to keep the Ten Commandments from being removed from public life.
It is sort of like drug laws. In a different time and place, I broke the law, and did not think it wise or prudent to legalize my activity.
I suspect I am not making much sense. So be it.
