What do you think the sword when found on islamic coutries flags means??
Its just a symbol, like we have an eagle. You give them too much credit. They live in the dark ages, that is why all the wealthy and/or intelligent ones move here.
I know many muslim doctors and small business owners. They love this country and are happy to be able to live in freedom. They hate the fundamentalist nutbags over there, thats why they left.
