Proverbs 17:28 Even a fool is counted wise when he holds his peace...
Proverbs 26:5 Answer a fool according to his folly, Lest he be wise in his own eyes.
First, the meme assumes there is such a thing as "good" and "evil." But "good" and "evil" do not exist in the purely material universe of atheism. All there is are mere chunks of matter undergoing temporal transformations according to the laws of physics. The only laws in a material universe are the underlying laws of physics. There are no moral laws. To put it another way, there is no such thing as "good" solutions of the laws of physics (e.g. a solution of the wave-function of the universe) or "evil" solutions. As has been often stated, there is no "ought" in physics, only what "is." If there are two future solutions, "X" and "Y," of the wave-equation, there is no physical reason the solution "ought" to be "X" rather than "Y;" and vice versa. This meme has to presuppose the existence of good and evil -- but to do so is to assume something that does not exist in the atheist universe; it has to assume theism. Such is the atheist's self-contradiction.
Second, this particular atheist, DJ, once commented in a prior exchange on social media, that the only things that are "real" are those testable by science and accessible via sense perception1 . This is a big problem for DJ. I asked him if he had ever seen, tasted, heard, smelled or touched a "moral law." Of course he had not; and, understandably, he offered no reply. He was caught in his own trap. Moral laws are not empirically accessible, they are not natural and they are not discoverable in rocks, electric circuits, or test tubes via the scientific method. By his own standard, "good" and "evil" are not real.
1 The view that knowledge is only obtained through sense perception ("experience") is radical empiricism. I addressed part of this prior exchange in the post "Village Atheism and Magical Configurations of Matter".↩
