As you wish.
Perhaps you will comment on this before you go:
Atheism can spread theistic awareness if someone were to call themselves an atheist when speaking to people who had no concepts of gods. Hypothetical situation, of course. But in that situation, the atheist would first have to explain the concept "gods" before he could move on to say that he didn't believe in them, and in so doing, he would have created awareness of theistic concepts in his listeners.
Atheism can bias our thinking because if the stance is "I believe no gods exist", it will be easy to prematurely reject ideas that involve aspects commonly associated with gods. If I start speaking of the universe as a singularity, about how I believe consciousness to be a fundamental aspect of this singularity, the bias we have from theism being forced on us makes it hard to see it as anything but theism, even though it is not. The atheistic bias will make many reject such ideas because of their similarity to theism.
This is how atheism can spread religious awareness, and how it can bias our thinking.
