I think there's some truth to it, I know that one of the things I felt when I finally let go of religion was a sense of freedom. Of course, for the JWs even growing a beard is a sin, so my desire to sin might not be atheistic enough for the theists here. But once you cut through the rationalizations you need to construct and see god as he is represented in the Bible, you shouldn't want to believe in him; he's terrifying. I guess that's why the other thing I felt was relief.
"Well, evolution is a theory. It is also a fact. And facts and theories are different things, not rungs in a hierarchy of increasing certainty. Facts are the world's data. Theories are structures of ideas that explain and interpret facts. Facts don't go away when scientists debate rival theories to explain them. Einstein's theory of gravitation replaced Newton's in this century, but apples didn't suspend themselves in midair, pending the outcome. And humans evolved from ape- like ancestors whether they did so by Darwin's proposed mechanism or by some other yet to be discovered."
