If evolution is not positive evidence for Atheism how rational is it to ignore the fact that all of you are evolutionists?
If evolution is not positive evidence for atheism, then it is very rational to ignore the fact that all of us (atheists?) are evolutionists.
I think you mean to ask if all atheists are evolutionists, then wouldn't it be rational to wonder whether evolution were positive evidence for atheism?
Well, actually, I know that isn't what you meant to say. For one thing, it's pretty coherent, and the connection isn't unreasonable -- maybe not true, but not unreasonable to investigate. Also, it presumes a question to be answered through reasoned dialogue, when you're pretty much stuck in your delusional black-and-white-all-questions-have-been-answered world.
Progress in human affairs has come mainly through the bold readiness of human beings not to confine themselves to seeking piecemeal improvements in the way things are done, but to present fundamental challenges in the name of reason to the current way of doing things and to the avowed or hidden assumptions on which it rests. -- E. H. Carr
