The last Soviet premiere was a Christian.
I find arguments (such as Dennett and Dawkins, and Hitchens) put forth that religion is the source of all evil in the world to be tendentious. Much evil has been (and continues to be) done in the name of a god, but the most nihilistic, murderous regimes in history, in the twentieth century, were godless. Belief in God (or lack thereof) is neither a necessary, or sufficient condition for evil acts. The real dividing line, as Jonah points out, is not whether or not one is a deist, but whether or not one is an individualist. Say whatever else you want about a classically liberal society–it might leave some behind, but it won’t murder them wholesale.
