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?
You don't think secular humans have guiding morals? There are many theories on the origin of morals, and religion is only one of them.
