Did you see the video of the man arrested after he attacked people in a London subway with a knife? “You ain’t no Muslim, bruv!” declared an onlooker.

Or, did you hear how Paul Ryan responded to Donald Trump’s call to ban Muslims from entering the United States? “This is not conservatism,” he said into the cameras.

I think Amber Phillips is right in her analysis of these two statements in her blog post at The Washington Post.

These moments of identity construction and group boundary maintenance are exactly the sorts of things us scholars of religion should be paying special attention to.
