That above is an atheist catchphrase that seems to never die, despite that it can very easily be demonstrated to be missing the salient point.
We’re not suggesting that people will be raping and pillaging with wild abandon the moment theistic ideas are jettisoned. Rather, we are pointing out the contradiction between what they say and what they believe.
They say they reject theism because of the lack of evidence. They believe absence of evidence is evidence of absence because of a prior metaphysical commitment to naturalism. In fact most intellectual atheists — or the more reflective of them, at least — admittedly subscribe to a naturalism of one sort or another.
Now, of course, with respect to the evidence for theism, I disagree, and that above is fine as far as it goes.
Until they deign to educate us on the immorality of our beliefs. Because the problem is that on naturalism, which is on which their atheism is predicated, good and evil simply do not exist.
What a naturalist sees as evil is really just a confluence of atoms that he happens to find personally distasteful. And he happens to find them personally distasteful because he’s been hardwired by evolution to do so, viz. his feelings of personal distaste, or any opinion he may have on what or what is not moral for that matter, are merely dispositions he had inherited that are the residue of an evolutionary history.
In other words, they are illusory.
He only has these set of moral opinions because they are, by mere chance, what made his ancestors, on the aggregate, survive. It thusly becomes not an objective fact of reality that, say, murdering babies for fun is wrong. In fact we can imagine an alien race having evolved in a way that would make them think that that’s a completely moral thing to do. Or a more terrestrial example would be the members of ISIS, say, who would opine to be moral that which we find immoral. And who are we to say they are wrong? Who are we to say they are evil? After all, these “evil” people are merely acting in accordance with how the atoms that comprise them happen to be arranged, and who, given naturalism, can say that one particular confluence of atoms is to be preferred over another?
So when an atheist-naturalist natters on about the ‘evils of religion’, it is a matter of logic that he might as well be nattering on about his choice of drapery, or about his choice of textile, or about the superiority of vanilla over chocolate. Because religion, or anything else for that matter, cannot possibly be evil in a universe where evil does not exist.
