There have been very few so called Christian extremist acts compared those carried out by Muslims ,the difference is the Christian extremists actions cannot be justified using the Christian religion,Muslims extremists can legitimately use the Koran to justify their acts of violence against non Muslims.
There are 1.6 billion Muslims and hundreds of millions of them believe in violent acts to impose Islam,we would roundly condemn people that espoused Nazi views and yet we tolerate a religion that is violent at it heart and is out of step with modern values.
