[1] The video that I posted [2] below of American Muslims stomping on and then ripping up an American flag comes from a New York-based Muslim group called the Islamic Thinkers Society. According to "Not just another Jihadi face: The Islamic Thinkers Society - Al Muhajiroun's identical twin in NYC" in [3] Militant Islam Monitor, the Islamic Thinkers Society is an American offshoot of the now-disbanded British jihadist group Al-Muhajiroun:

The radical Islamist Al Muhajiroun, appears to have surfaced in Queens under the oxymoronic name of the Islamic Thinkers Society aka Intellectual Thinkers Society. The groups North American spokesman, Kamran Bokhari, is now working as a strategic analyst for Statfor - Strategic Forecasting Inc. run by George Friedman. Stratfor who also employs ex government counter terrorism analysts has dubbed Bokhari their "in house Jihadi"
