The nonexistence of God is nothing more than a nonsense option. The categories of good and evil themselves require some sort of transcendent standard. What makes things good? What makes things evil? Atheists have, by and large, given up on the idea of an absolute standard of morality. After all, spiritual emptiness and the nonexistence of anything outside of the simple material universe is no way to come up with an ethical system. Morality is cultural preference (which cannot be said to be right or wrong) and fundamentally relative. It takes on (to be generous) the same authority as Wisconsin speed limits on a Nevada highway at night.
People are raped in this world, and rape is evil. Because evil exists, there must be no God. Because there is no God—no authoritative standard over creation—the badness of rape downgrades to a mere matter of societal taste. Ethnic cuisine, ethnic ethics. In God’s absence rape is no longer fundamentally evil. In our country, you’ll get confined to a cell (if caught and convicted), but that just means we enforce our taste, not that our taste has any real authority over anyone else. In other societies, girls have been passed around and traded like baseball cards. Is that right? Is that wrong? You like exploitation; I like apple pie. The two discussions exist on the same plane. There’s no such thing as moral and immoral. In this country, we eat gyros. In this one, we eat pizza. And we’ll give you a ticket for jaywalking. . . .
I’ve watched the Discovery Channel. I’ve enjoyed the Discovery Channel. But in that world, if I want to reproduce with you (or tear you limb from limb) I just need to be bigger and stronger than you are. You look pretty small and a little sickly. Shall I feed you to my young? Why not? Cannibalism might not be condoned in your culture, but it has a long and storied tradition in mine. Are you saying that your culture is superior, that it is somehow right while mine is wrong? You’re being a racist, but likely you’re still small, and even racists taste good in casserole. . . .
