"Secular ideologies - socialism, positivism, and so forth - promised a world free of bigotry and hatred, and an unending vista of peace and prosperity. Humankind, however, has vomited up these ideologies. Secular Europe and radical Islam in that sense represent two sides of the same coin: both have rejected the secular order, the latter through open battle, and the former through fatal resignation."

That article is religious propaganda very thinly masked as science. Don't listen to it.
