A preponderance of atheists hanker for moral relativism, and as such, their foundation in conflict with the standards of virtue necessary for a free and prosperous society. It is not that no atheist can abide or thrive under such conditions, but that most of them prefer amorality and relish the confusion that ensues. There is danger in setting up the individual as the sole arbiter of right and wrong; in rugged individualism. A virtuous, prosperous society will take measures accountable also to, and for, the neighbor.
I call BS. Prove it.
I don't care what my neighbor does, unless it is something that demands I shoot him or her.
