I ran across this verbiage which comes from Eisenhower's Farewell Address. A link is below. I reproduce it because of his derogatory reference to atheism. I want to convey a historical perspective of atheism to show how it had been negatively referenced.

He says "We face a hostile ideology---global in scope, atheistic in character, ruthless in purpose, and insidious in method."

The whole paragraph reads:
Progress toward these noble goals is persistently threatened by the conflict now engulfing the world. It commands our whole attention, absorbs our very beings. We face a hostile ideology---global in scope, atheistic in character, ruthless in purpose, and insidious in method. Unhappily the danger it poses promises to be of indefinite duration. To meet it successfully, there is called for, not so much the emotional and transitory sacrifices of crisis, but rather those which enable us to carry forward steadily, surely, and without complaint the burdens of a prolonged and complex struggle---with liberty the stake. Only thus shall we remain, despite every provocation, on our charted course toward permanent peace and human betterment.
