If, as the fundieists claim, there is no basis for morality other than their giant man with a long white beard who lives on clouds, why are prisons full of fundies but lacking in atheists? Could it be fundies have no guide to right and wrong? So yes there is a connection between fundieism and social evils. A good example would be Nazi Germany and the murderous sentiments Hitler espoused.
"We were convinced that the people need and require this faith. We have therefore undertaken the fight against the atheistic movement, and that not merely with a few theoretical declarations: we have stamped it out."
- Adolf Hitler, 1933 speech in Berlin
"... I do not merely talk of Christianity, no, I also profess that I will never ally myself with the parties which destroy Christianity."
Adolf Hitler, February 15, 1933, speech in Stuttgart
"National Socialism neither opposes the Church nor is it anti-religious, but on the contrary, it stands on the ground of a real Christianity."
Adolf Hitler, August 26, 1934, speech in Koblenz
"This human world of ours would be inconceivable without the practical existence of a religious belief."
Adolf Hitler, Mein Kampf
"I may not be a light of the church, a pulpiteer, but deep down I am a pious man, and believe that whoever fights bravely in defense of the natural laws framed by God and never capitulates will never be deserted by the Lawgiver, but will, in the end, receive the blessings of Providence."
Adolf Hitler, 1944
