If White people were doing the things Islamic extremists are..Wouldn't Islam be branded racist?

The basis upon which terrorism and extremism is built is largely debated but it is mainly associated with Islam because it is a very small minority of muslims that make up the majority of the minority that go down this route what you have to keep in mind though is that it is not the entire religion or ethnic group that choose this path. It is mainly those in countries whose main religion is Islam where there is heavy western presence that extremism arises. One of the main causes is a dislike of what they view as the gradual imposition of western culture in these countries whose traditional Islamic values are quite different in effect what they are arguing they are fighting against is a modern type of colonialism but there are much more complicated dynamics in the rise and persistence of extremism but if the western-islamic culture clash is the main reason then you are right if the roles were reversed white people would be called racists. If the west starts to put such labels on extremists it would not be conducive to any favourable result it would simply further inflame the situation don't you think because there is a largely accepted belief whether it be an ideology to legitimise such violence or the truth that this is built on achieving peace through Islamic principles and values, don't quote me on this because I am not an expert, which would be against such things as racism. Comparing the death tolls of atrocities committed through history on the basis of tit for tat comparatively between races is really quite vulgar by the way.
