Well that's part of the explanation.
At least 80% of American mosques are controlled and were built by the Saudi Wahhabis and through ISNA, the Islamic Society of North America, which is controlled by Saudi money, the radical Islamists control American Islam.
These people stomp on the most moderate ones.
The Chicago Trib or the Sun Times did a story last year on what was going on in area mosques and when the MSM starts picking up on it, then it must be far worse than it seems.
In short the radicals have done a very thorough job in supressing those that they disagree with.
