The ways in which the New Atheism serves imperialism are manifold. It bolsters the “clash of civilizations” narrative used to justify ventures like the invasion of Iraq and the need for repressive measures like state surveillance.

The dating of the books may be commonly stated to be past AD80,... Read more →
