[Mara] Einstein and the Theory of [religious] Relativity

iTunes search for "Douglas Rushkoff" produces this CUNY podcast of a forum featuring our search subject and Mara Einstein, who is hocking her book Brands of Faith. She is cogent and unafraid to disagree with such a sage as Rushkoff. I'm interested.

Order the book. Begin reading. Find this:

". . . religion is a commodity product. The majority of religions offer same end benefit for the consumer (salvation, peace of mind, etc.). Though packaged differently, fundamentally they are the same product, no different than buying one shampoo versus another."
