I don´t understand these folks who want Islam to have a `Reformation´. Don´t they know anything about the western Christian Reformation of the 16th century, it´s leaders and it´s consequences?

Let´s see:Martin Luther(1483-1546) was an antisemite who claimed that aristocrats could ensure their place in heaven by killing rebellious peasants and he congratulated Ulrich Zwingli(k.1531), a Swiss Reformer, after the latter had murdered leaders of another sect by drowning them. Later Zwingli fell himself in battle. Jean Calvin(1509-1564) was a petty tyrant who executed children. And so on. These weren´t nice folk by any standard and even if the Netherlands may have partly flourished because of the Reformation, Germany certainly stayed largely a backwater until the 18th century because of the Reformation. And one shouldn´t forget the religious wars that decimated Germany in the in the 16th and 17th centuries and the Huguenot war of France between 1562 and 1598. And the Catholic backlash wasn´t exactly a complete triumph of humanity and humanistic virtues either.
