"With a billion members, Islam must be the world's largest religious cult."

I think you're being overly nitpicky...with several billion members, the entire cult of organized religion is the "world's largest religious cult"...

The differences between Islam, Judaism, and Christianity are so miniscule, and the actions of their zealous followers are so closely matched as to be indistinguishable, that it is almost a waste of time to even refer to them as "different cults"...they're not even on diffferent sides of a coin, they're all running in circles on the same side of the same coin.

Fish on...
