“In 1998, Sheikh Muhammad Hisham Kabbani, a Sufi leader, visited 114 mosques in the United States. Then he gave testimony before a State Department Open Forum in January 1999, and asserted that 80% of American mosques taught the ‘extremist ideology.’
Then there was the Center for Religious Freedom’s 2005 study, and the Mapping Sharia Project’s 2008 study. Each independently showed that upwards of 80% of mosques in America were preaching hatred of Jews and Christians and the necessity ultimately to impose Islamic rule.
And now comes yet more confirmation that mosques in the U.S. are teaching these things, and again the percentage is remarkably similar: around 80% of mosques are found to be teaching jihad warfare and Islamic supremacism.
