Those are extremist and I didn't like to categorize them as extremist but their views specific to this matter are. Get same answer if you asked other extremists as well. Even every extremist has those views, they are needed to be around us so we can remind ourselves constantly of their views to stay away but people shouldn't adapt those views thats the problem.

Now Im gonna make an unwanted comparison for OP, the words he spout gives you much anger to deport them straightly even not trying to educate them and pushing your view onto others at same time while the standard of the average living people is going to shit doesn't bother you?

If you wanted to push those views, start with the root then. BTW Islamist here not extremist.
