At face value, and by its own understanding, New Atheism is a reinvigorated incarnation of the Enlightenment scientism found in the work of thinkers like Bacon and Descartes: a critical discourse that subjects religious texts and traditions to rational scrutiny by way of empirical inquiry and defends universal reason against the forces of provincialism.
In practice, it is a crude, reductive, and highly selective critique that owes its popular and commercial success almost entirely to the “war on terror” and its utility as an intellectual instrument of imperialist geopolitics.
