There are exceptions. There are Muslims out there who recognize Wahhabism for the revisionist kind of violent, intolerant, hateful belief it is, which is responsible for not only acts of violence against non-Muslims, but also against those Muslims who disagree with its agenda of intolerance, violence and hatred, like the Sufi sect - a pacificistic Islamic group pretty thoroughly stamped out in the Saudi Sheikdom by the Wahhabist majority there.
Also, since the Wahhabis control the sacred places of Islam - Mecca, Medina, etc, as well as the petrodollars of the Sheikdoms, they wield immense power in the Islamic world. Finally, most Mosques in the U.S. and western Europe are run by these vile and vicious people.
There is much in Islam that is admirable. Muslims DO worship the same God we do. But there appears to be considerable dichotomies in several parts of the Koran and the teachings of Mohammad, and a large gap exists between the perception of Islam as a "peaceful" religion and its practise in many parts of the world.
Regardless of how this writer presents his arguments and how one views Islam in general, Wahhabism is a vicious, dangerous, violent, anti-western and anti-American cult and, as such, neither it nor its practititioners should be protected within the United States or indeed withi the borders of any civilized western nation.
What I have said about Wahhabism can also be extended to Shiism.
