Muslims who have simply inherited islam as a kind of cultural identity and don't follow it except superficially have no idea it is Satanic. Many muslims in name only would dump it were family and community pressures not so great.
And then you have the ex-muslims like Ergun Caner (Dean of Students at Liberty Univ) and Walid Shoebat, an avid warrior against islam.
Not all muslims are bad...but having said that, I don't know where the line is to be drawn between those who are truly devoted to the Satanic allah and those that might be eventually rescued from that evil.
