Enter no conflicts with fanatics unless you can diffuse them. Oppose a religion with another religion only if your proofs (miracles) are irrefutable or if you can mesh in a way that the fanatics accept you as god-inspired. This has long been the barrier to science assuming a mantle of divine revelation. Science is so obviously man-made. Fanatics (and many are fanatic on one subject or another) must know where you stand, but more important, must recognize who whispers in your ear.
