The 10 Commandments was written for a purpose. Those human vices for which it was written are the same vices that the Left exploits for their pursuit of power and control.
The Left always appeals to all that is base in the human character. The reason is not hard to fathom.
While there are a few demagogues who simply exploit the base tendencies, most of those on the Left are compulsion driven. Hating the reality that we are all different--and hence each responsible for our own performance--they seek fantasy driven wish lists, that deny reality--and they do so with a fervor that says much about the neurotic compulsions that substitute for human reason.
