>In what way is atheism a danger or harm to society except that it violates your proposed monoculture?
Violating said monoculture is a problem in itself because it leads to a population that cannot collaborate or agree even broadly on morals that concern day to day life. We're seeing this right now in America, where each side of the aisle (which broadly speaking is cut across religious lines) is becoming progressively angrier as they realise the others beliefs necessarily requires capitulation from their side on some issues, in ways that cannot be accepted, such as abortion or the integration of homosexuals and transgenders. This is gradually destabilizing the country.
