Does proper parenting prevent any and all dalliances into dark and dangerous areas by ones children? Not even. But, without due diligence on the parents part, a foray into such areas usually means a life long problem for the children, and by default, society. Ergo, politicians arise to cure the problems with an ever blossoming tree of laws.
The letter killeth, the spirit giveth life.
If my child had no experience in dealing with darkness, he would eventually succumb to it. Do you want minimal laws? It begins at home with the fear of God....not Buckley.
My God is more about love then fear.
Forgiveness, rather then condemnation.
Charity, rather then greed.
Humility, rather then know it all vanity.
And there will always be those like Thomas Jefferson who diagree with your way of looking at politics as when he wrote the following...
"We discover in the gospels a groundwork of vulgar ignorance, of things impossible, of superstition, fanaticism and fabrication ."
Perhaps personal religious beliefs should not dominate political discussion...at least until there is some sembelance of uniformity in the various beliefs.
