There is no such thing as "extremist Islam."
There is only Wahabbism.
There is no such thing as Islamofascism.
There is only Wahabbism.
And Sunnites condone every bit of it.
"All that is necessary for the triumph of evil is for good men to do nothing."
And that's exactly what Sunnites do -- nothing...some Wahabbis (also go by Salafi) clerics have chosen to justify suicide bombing as a extreme, yet necessary form of Jihad. As you may or may not know, in their minds, their fatwas > Qur'an.
Some Wahabbis also have found it necessary to put radi Allah anhu after the accursed Yazid. As you may or may not know, in their minds, their sahaba > Ahl al-Bayt.
There is no such thing as Wahabbi Islam.
There is only Wahabbism.
