regarding:
We have little doubt that the vast majority of Gülen’s followers have nothing to do with these tactics and would not condone them. But they are being ill-served by the movement’s leaders, whose own deception and hypocrisy are the movement’s worse enemy.
How do you know what the “vast majority” of his followers believe. If the “vast majority” of his followers are muslim, they are Jewhaters.
Takkiya and kitman are sanctioned islamic behaviors, celebrated in the hadiths and koran-whay we call deception and hypocrisy are encouraged behaviors when trying to make islam supreme in the world (jihad).
