It may be true that A.Q and other exstremist groups want all non muslims dead or converted to follow islam. But it is the policy of the west and the current and past superpowers that provide cause for non exstemist people to hear and see the actions of the west and decide that we are against muslims in general ( be it true or not ) and conclude that these exstremist representitives of the islamic faith are upholding the honor of islam. It isn't hard to come up with a number of actions by the west that supports their argument of us against them. The same old answer and reason used by the west is that they are jealous of our democratic society and what we have achieved. It's the other way around, we dont like how they live and what they call normal society.
