The narrowness of the schoolteacher subculture; the confusion between form and substance caused by over-reliance on a written Constitution; and Political Correctness. These three blights on American society have combined to bring about a lunatic reversal of the meanings of ‘secular’ and ‘religious’ in school curricula:
On the one hand, the teaching of the foundation stone of the United States' secular political culture, the Declaration of Independence, has been made taboo on the grounds that it constitutes ‘religion’.
On the other, Muslim missionary work in American schools is being encouraged on the grounds that it is ‘multicultural’ – i.e. promotes secular values.
