Scientology is the purest example of purposeful calculated evil I have ever personally experienced. Even the depredations of the left are nothing compared to the crimes that Scientology commits on a daily basis. If there is such a thing as an anti-christ, Hubbard is a strong contender for the title.
Everything that Scientology touches turns to rot. It destroys families. It brings about financial ruin. It takes free men and women and turns them into slaves. Trying to think of something, anything, that this cult does which is good is very difficult. I cannot think of anything that it does which is good.
Scientology is the creation of a sociopath. It is the will and temperament of that sociopath Hubbard made manifest in the world.
This is my criticism of the cult. The sooner it is extinguished from the world the better.
