F'm!  Until Muslims around the globe step-up and take back what they say is a peaceful religion, they stand in the corner.  This is a primary reason multi-culturalism is an absurd idea.  It's an oxymoron created by the extreme left.  There are different cultures all over the planet.  They exist on their own terms, and provide opportunity for understanding and awe, but shallow is the thought process that believes all these different cultures have a desire to blend, or should be forced to. That's an extreme left ideology that has no basis in fact.
