Only suggestion I could think of is Muslim Cult.
I’m not opposed to it. They certainly exhibit most of the characteristics of a cult.
Well, that’s what I thought until I looked up the word cult. I wanted to see the definition, and thought Islam would match up on a number of points.
What I found was that you could pretty well place all religions in this group. All but one definition would apply to all religions.
I can’t help but wonder if the definition of cult hasn’t been re-crafted in recent times to make it possible for the anti-religion groups to trash all religions.
