Atheism is a faith as much as any other. Agnosticism says "don't know".
Those who are certain that there is no god and want Him removed from public view are pushing their own "no god" God down our throats.
Whether there is discussion of the mechanisms by which a creator designed the universe or not is irrelevant, we'll never be able to say with any certainty how things happened. Can we create life from basic components? Not taking egg and sperm, but carbon, et al?
For science to insist that God played NO ROLE in the creation of the universe is to institutionalize that there is no god. If God had no role, all of this expansion surely must have come as a surprise to Him. How did God evolve into being? Or is science adamant in saying that He doesn't exist?
Beware of Atheism and State, the defacto state sponsored religion.
