Without an absolute, guiding moral ideology, and I don't think secular humanists have that, you're left with the bad of human nature and none of the good. Why did the grand Marxist experiment degenerate into a country run by corrupt oligarchs in a very short time on the scale of human history?
Mostly because they had no Constitution which limited the power of the Executive Branch.
Absolute power does corrupt absolutely, whether that power be contained in a Theocracy or a Socialist Democracy.
People who choose to brew up their own storms bitch loudest about the rain.
