Professor William Egginton argues as much in his book, In Defense of Religious Moderation:
Whether Christian or of other faiths, the movements we call religious fundamentalism are always the result of a perceived attack on a given community of faith. This is one reason why the attempt to regulate or restrict religious practice, what the new atheists are in essence calling for, has always resulted in and can only result in more fervently held beliefs, often in the form of fundamentalist backlash.
He offers the Scopes “Monkey Trial" as an example:
[B]efore the Scopes trial few fundamentalists actually believed in creation science or thought it particularly important to do so. Creation science became a hot-button item for the fundamentalist movement only after William Jennings Bryan’s defeat in court by Clarence Darrow was ridiculed by the journalist and essayist H. L Mencken, who wrote in an obituary for Bryan that he “lived too long, and descended too deeply into the mud, to be taken seriously hereafter by fully literate men, even of the kind who write school-books.” In the face of such humiliating condescension, groups tend to close ranks around tenets and practices that define them as different from the outside world.
