The bad part if the anti religion myth is the obsessive negativism some people opposed exhibit, here and elsewhere.

It surely must take much "dark" internal energy to focus on maintaining a myth (with little actual evidence) that none of the millions of people currently experience any positive benefit-socially, personally or otherwise, from their association with an organized religion, or in a belief in a God. A myth that seems to be well maintained in some obsessive anti-God and religion quarters, sometimes masquerading as logical thinking.
