There are many things wrong with Scientology, mostly the same things that are wrong with most religions, believing something only because we want to believe it.
But here in this FOD excerpt from the HBO documentary GOING CLEAR we find the real horror behind Scientology which sets it apart from stonings, beheadings, executions, talking snakes, killing your son, dinosaur hunting, living in fish, Zombies, walking on water and other more accepted and reasonable religious beliefs.
For instance we find that in Scientology people take out all the M&Ms from the trail mix, that the coffee in the building is just so-so and Tom Cruise is short.
