Intolerance

 D.A. Carson’s book The Intolerance of Tolerance:
This shift from “accepting the existence of different views” to “acceptance of different views,” from recognizing other people’s right to have different beliefs or practices to accepting the differing views of other people, is subtle in form, but massive in substance. To accept that a different or opposing position exists and deserves the right to exist is one thing; to accept the position itself means that one is no longer opposing it. The new tolerance suggests that actually accepting another’s position means believing that position to be true, or at least as true as your own.
