How is that a valid indication that all atheists are communists? In a poll sampling people from former Communist (note the upper case 'C') countries in which atheism was officially maintained as a part of Party policy, one would expect that those holding on to their party identity would retain that feature of said identity. Claiming that this highly biased sample is universally representative of atheists is like conducting a survey in Vatican City and then claiming that it indicated that all Christians are Catholic.
You can as well recite from the Book of Ezekiel. . .
You twist stuff around again the way communist/atheist propaganda used to. I never said that all atheists are communists. All I said is that atheism is a synonym to communism. If you suspect that there is a relationship between atheism and communism given the fact that the doctrine-makers Marx and Lenin were atheist, and you conduct the poll in communist countries, then the conclusion is pretty clear. Btw, ways and means don't deny existence. (Didn't Eichmann receive orders to take care of the Jews from Hitler? He was forced, of course. But your defense didn't do much for him. He got a rope.)
Atheism in the communist countries was an active pseudo religion that chased theists around. Since the Founding Fathers were not atheists, you can only twist around things that other people said -- just do a tiny fraction of the evil that the commies did.
Atheism can't serve as a vehicle for social changes any more, so it's very unlikely that it would ideologically support some crappy political systems once again.
