What is "intolerance" on the part of "anti religionists?" I don't know of any atheists/agnostics, or "non religious" folk who want to prevent anyone else from believing/practicing whatever they like - until said practice involves others. Which is where "church & state" issues arise. Arguing against religious points of view is not intolerance; punishing or preventing the practices arising from those points of view is, and I don't know of anyone seriously attempting to ban religious practice. Would be grateful for correction, of course.
