Nu-atheism always had a white chauvinism element to it, which was why it was so quickly weaponized to serve Islamophobic ends. Their whole understanding of history is that humans were enslaved by superstition and religion until a certain group of humans (ie white people) realized that superstitions and God aren't real. Their partial freedom from the God delusion lead to a flourishing of human thought and achievement, first realized as the Enlightenment, which then lead to them ushering forth the Industrial Revolution upon which their thriving societies are built on. The rest of humanity is stuck as backwards people living in mud huts thinking praying to the rain god would give them rain because they're still enslaved by superstition and God, so it is the duty of the atheists of the secular world to free the rest of humanity from the darkness of God.
This is just typical missionary white chauvinist bullshit. It's no wonder they would eventually "find God" again once it became more in vogue to embrace religion. Perhaps the rise of China has something to do with it. Once a non-European country ruled by an atheist ideology begins to rise, suddenly "atheism is the key to human progress and civilization" begins to lose its luster.
