Not so fast. The theory of neutral drift, which is what you were arguing in your post is false. Adding natural selection to it does not help evolution because evolution does not create anything, it does not create new genetic information, new genes, new anything. Natural selection only destroys so adding -2 to 0 does not give you 4. What it does give you is a theory which is total nonsense - evolution.
Incidentally, I worked a period of time for the U.S. Embassy in Soviet Russia and where your above description may've characterized its government, it certainly did not characterize its people. In any case, I could apply the exact same characterization to any number of theistic governments quite easily. Doing so would not serve to establish anything of value about their underlying religious pretenses.
