And note that Holder and Smith agree that there is a difference between "Islam" and "radical Islam" and that the latter is a misinterpretation of the former. On what grounds do they believe this? Where is this peaceful, benign version of Islam that teaches peaceful coexistence with unbelievers as equals with believers in a secular society on an indefinite basis? No one has ever produced it. But everyone believes it exists.
