Define it however you wish, it is a code of morality which you wish enforced by men with badges and guns, that can put people in cages or cemetery plots. How does that make you any different than the religious/moral conservatives who want their code enforced by the same badges and guns?
When I am forced to do a thing, my agency is abnegated; meaning that there is nothing moral about doing something that I am forced to be doing. Without volition, there is no such thing as morality.
It is kinda curious to me how lefties can be at once so cynical about mankind, men who have little or no power, and then be so naive about giving those same men he doesn't trust with deciding for themselves who will be the objects of their benevolence, the power to rule over other men. Are we to believe that our politicians and bureaucrats are made from a finer clay than we are? That is simply not credible.
If the people in government are no more trustworthy than the rest of us, if mankind is pretty much bad, how is it prudent to give bad men power over us? How does that work out where you don't end up with Venezuela, Cuba, USSR, and China?
I'm certain that almost nobody in Venezuela voted for what it is that they now have, yet what they now have is the [inevitable] outcome of how they've voted for the last 20 or 25 years. There is no moral or smart enough person or people to be entrusted with that kind of power.
That is precisely the reason it should be discounted. Accretion of power to the government leads to invariably bad consequences for a lot of people, including and most especially the true believers.
