David Theroux of the Independent Institute has an excellent essay on Secular Theocracy
The Foundations and Folly of Modern Tyranny (emphasis added)
We live in an increasingly secularized world of massive and pervasive nation states in which traditional religion, especially Christianity, is ruled unwelcome and even a real danger on the basis of a purported history of intolerance and “religious violence.” This is found in most all “public” domains, including the institutions of education, business, government, welfare, transportation, parks and recreation, science, art, foreign affairs, economics, entertainment, and the media. A secularized public square policed by government is viewed as providing a neutral, rational, free, and safe domain that keeps the “irrational” forces of religion from creating conflict and darkness. And we are told that real progress requires expanding this domain by pushing religion ever backward into remote corners of society where it has little or no influence.
