“ Radicals have value, at least; they can move the center. On a scale of 1 to 5, 3 is moderate, 1 and 5 the hardliners. But if a good radical takes it up to 9, then 5 becomes the new center. I already saw it working in the American Muslim community. For years women were neglected in mosques, denied entrance to the main prayer halls and relegated to poorly maintained balconies and basements. It was only after a handdful of Muslim feminists raised lunatic fringe demands like mixed-gender prayers with men and women standing together and even women imams giving sermons and leading men in prayer that major organizations such as ISNA and CAIR began to recognize the moderate concerns and deal with the issue of women in mosques. I've taken part in the woman-led prayer movement, both as a writer and as a man who prays behind women, happy to be the extremist who makes moderate reform seem less threatening. Insha'Allah, what's extreme today will not be extreme tomorrow. ”
