First of all, you are making up rules as you go along..which I guess shouldn't surprise me, considering the subject matter, and your stance.
The proofs of what I am saying are legion. The Soviet Union, Nazi Germany, Cuba, China, the Eastern European dictatorships, African dictatorships, South American dictatorships, etc., etc....they all thought they were smart enough to go it alone without the Creator. Where did it get them?
You accuse me of using generalities...just how specific do I need to be?
The American Republic prospered because it had Christian morality as its mainstay. The French Republic ended in blood and tyranny, because the French sneered at God, and decided they were smart enough to come up with their own rules for civil society.
(Of course, all of these societies who destroy themselves in this way in this generation come crawling to us for help in cleaning up the mess they have made...and we invariably help them out. Why? Because that's what Christians do.)
As for evidence in history or reason, show it. Pointing out infamous atheists to "prove" your point is the spotlight fallacy.
Would you rather I picked some obscure ones? :-)
