" The same benefits misleadingly associated with religion — security, spiritual comfort, dogmatic relief from doubt — are thought to flow from a therapeutic politics of identity. In effect, identity politics has come to serve as a substitute for religion — or at least for the feeling of self-righteousness that is so commonly confused with religion.
These developments shed further light on the decline of democratic debate. ‘Diversity’ — a slogan that looks attractive on the face of it — has come to mean the opposite of what it appears to mean. In practice, diversity turns out to legitimize a new dogmatism, in which rival minorities take shelter behind a set of beliefs impervious to rational discussion. "
