Your main leader on religion as a growing force in the Arab awakening is warily measured (“Islam and the Arab Revolutions,” April 2, 2011). North Africa and the Middle East are in turmoil. Farther east, trouble is brewing, as well. Although you advise caution, for radical ideas are afoot in the Muslim world, you also see hopeful signs for democracy. “Islam will never find an accommodation with the modern democratic world until Muslims can take responsibility for their own lives,” you conclude gingerly. True enough. But you fail to point out that there is also an important interplay between the Muslim and Christian worlds. Worryingly, there are fundamentalists on both sides of the growing divide, and they thrive on religious conflict. Shortly after you went to press, a score of people was killed in Afghanistan as a consequence of Koran burning in America less than a fortnight earlier. Excesses of Christian fundamentalism in America will most likely persist. Even Northwestern Europe is not spared from them, as witnessed by pernicious political undercurrents in the Netherlands and Denmark, for example. There are religious fundamentalists all around, and they must be taken into account even when Islam is in the limelight.
