Trump is of course right in what he says as is Hannity the Islamic belief structure is not compatible with what we call Western Civilization. Meaning personal freedom and a representative government controlled by the citizens. It is technically impossible for a Muslim to life his life in e.g. America and practice his beliefs in accordance with Islam doctrine as codified by Sharia Law. Since this is a 100% true statement then any Muslims that are here can be turned into Jihadists by any cleric that wants to do so since Jihad is the way of life for devote Muslim men.
