I don't see atheists organizing for the sake of changing public policy but I do see Fundamentalists in 'full-frontal attack mode' and "weirdly obsessed" in doing so.
WIth respect to the part of your post I highlighted, mkl, the 'proof' depends on what is being referred to as 'black and white'.
If this is a reference to the existence/non-existence of deity (as I assume from the context of that part of the article), then I would think all the proof required is in the label 'atheist'. The use of 'aggressive' as a descriptor of the zealousness of the atheists is irrelevant, imo.
