What is occuring between the Islamic world and othe cultures is not a simple disagreement of ideology. If it was we could ignore the debate. It is a war and doesn’t require full support of every group member to be waged. If it did the US would never use the military. Like it or not every group is lumped together based on the acts of the most visible. It has always been this way and always will be. We like to think that societies have evolved but culturally humans still have the same behaviors that existed from the beginning.
