That is a perfectly valid to a point, however, many people of a 'spiritual' perspective get a litle fed up with being shouted at by atheists and empiricists. Amon Ra, Vishnu et al are entirely symbolic.
Dawkins and his fellows have no knowledge of deeper spititual/esoteric knowledge systems whatsoever. Thus, their railing against this fictional cloud bound anthropomorhic entity are entirely irrelevant in that context.
