Non-Islamic, non-foreign-motivated terrorist actions have killed at least as many Americans on American soil as those who were promoted by jihadists.

The underlying struggle - between worlds of plenty and worlds of want; between the modern and the ancient; between those who embrace our teeming, colliding, irksome diversity, while still insisting on a set of values that binds us together, and those who would seek, under whatever flag or slogan or sacred text, a certainty and simplification that justifies cruelty toward those not like us.
