I have long contended that Islam is unique among the major world religions in having a developed doctrine, theology, and legal system mandating warfare against and the subjugation of unbelievers. There is no orthodox sect or school of Islam that teaches that Muslims must coexist peacefully as equals with non-Muslims on an indefinite basis. I use the term radical Islam merely to distinguish those Muslims who are actively working to advance this subjugation from the many millions who are not, as well as to emphasize that the stealth jihad program is truly radical: it aims at nothing less than the transformation of American society and the imposition of Islamic law here, subjugating women and non-Muslims to the status of legal inferiors.
