Calvin or Luther

While some outside of Islam have expressed hope for a Reformation-type event within the Muslim faith, I see no indication whatsoever that any reformer has arisen in centuries. Sure, there are brands within Islam that are less aggressive than the Twelvers in the Islamic Republic of Iran or the Sunni Salafists or followers of Wahhab, but they are a tiny minority, often persecuted by the more militant strains. I would not be worried if my neighbor was a Sufi dancer, but my fears would be palpable as an American Jew if my neighbor characterized himself as a devoted "Wahhabi".
