If yu think JW'S Are a cult or the Mormons or Scientiologists think again. Wahabi muslims and all their adherents are indoctrinated a hundred times more.
How successful is the movement in exposing these three cults. Realistically speaking? Now imagine the insurmountable task of getting billions of Muslims to get out of cult mode. Mohammed was the father of this cult. And he has rivited his teachings into the minds of his followers so deep that even a nuke won reach it to dislodge.
I would advocate reading the Quran to understand the extent of the madmans cultic teachings. English translations are available although they won't call it "translations" since their god wanted them to read his words only in arabic.
