Scientology - Controversy?

Interesting, I've been reading The Scientology book Advanced Procedures and Axioms by L. Ron Hubbard. Great information especially about efforts and counter efforts. So this brought up the so called controversy about Scientology which I am now understanding. In the book there's lots of information about destructive and constructive personalities.

Unfortunately, there are those who oppose betterment activities because of the misguided motivation that to survive they've got to keep others down. Unfortunately, individuals like this could be intelligent and well spoken but they run their lives from the viewpoint that "if others are strong, I wouldn't succeed." This sad state of affairs of this type of individual is behind the controversy of Scientology. Something that truly helps like Scientology drives this kind of personality wild so they set up web sites, spread rumors and worse since Scientology really helps people - what could be worse for the dominating, nullifying personality than his/her victims getting strong and better?

Think for yourself. Read Scientology from the source and make up your own mind.
