If someone wove islam into the fabric of America, there needs to be a really good weaver brought in to cut it out and patch it with something good.
The reason he would say ‘Islam Has Been Woven Into the Fabric of Our Country Since Its Founding’ is that it gives them a claim. Once they have (ever had) a claim, they say they have a right to retake that area and make it theirs.
That is what they have been doing for the last 1/2 century in Europe since they were kicked out several hundred years earlier.
