Rigid materialists, Fooles, to my mind, are sadly impoverished, unable to feel and absorb nuance and depth. When it comes down to it, what harm is done by those who do believe there is much more to be experienced than is discerned or admitted by a-theists?

Like anything else, the misuse of 'spiritual' gifts is the issue. NO ONE should go to war, for instance, in the name of their god nor, on a smaller scale, should anyone resort to violence in arguing their belief.
