There could be a hidden assumption behind Graham's idea, which is that everyone (that matters) shares his beliefs. Often in the West, secular liberalism is the assumed religion and news articles, books, conversations all implicitly assume it. To people completely immersed in this paradigm, religion is merely external decoration, like a costume, that is exterior to an assumed identical core belief. People who make this assumption got a rude shock around the time of the ISIS attacks, when they found that some people who grew up in French housing estates behaved in extremely strange and troubling ways. Ideas have consequences, and religion is the set of ideas about the matters of utmost consequence. These ideas are inherently part of people's identity.
