Innate Morality is a Tacit Moral Equivocation. If humans are innately moral all human morals are equal. Cannibalism in Papua New Guinea is moral. Human Sacrifice is moral. Muslim genocide, slavery, child rape, sex slavery, & Terrorism is moral.
Atheism is not a Moral Authority and if it was it would be a Religion. Atheism is Moral and Philosophical Anarchy. There are no Atheist Morals because Atheists have nothing in common but the absence of a belief in God or the hatred of God.
A muslim who converts to Atheism still wants Israel destroyed and is comfortable with Christian Genocide.
It is the Laws & Punishments of a Society that make us Moral. And those can’t be agreed upon by Atheists because they have no Highest Form of the Good or God that they Reveal. Which is why their has never been & never will be a Great Atheist Civilization. The most secular nation is Israel with almost 50% Atheists and they’re Constitution is still is inspired by the Talmud.
