fiveyearzen, welcome. I saw your other thread. Personally I think it is great that a teacher is educating themselves about scientology.
So what was it about scientology that appealed to my youthful, misinformed idealism (I was a young "lost" 24 year old when I got involved)?
Firstly I was naive. Not knocking myself for stating that - just the truth. I was concerned about the madness in the world. I saw other groups as esoteric & irrelevant to modern-world problems. How could praying make the world better for the next generation? How could localised pockets of "doing good" fix this mess? To really get down to the core of what was wrong with the world, I liked the idea of eradicating the insanity each man, woman & child carried. Audit out that insanity and wow, the world would become beautiful.
Scientology hooked me in with the word "practical". This was a practical way I could participate in changing the world for the better. It was offered as "workable". In a world full of non-workable, half-baked theories, I liked the concept of being part of something that would do what it said it would do.
Of course in retrospect, wallowing in the benefit of hindsight, I see the only "world" that scientology
really changes is its own. Scientology manipulates the "outside world" for its own gain. But when I was first becoming involved with the group, I was hooked by the concept that
this was the way to develop a brand new world, based on sanity & peace. This was hugely appealing to me.
As my years within the group passed, I retained this view. I was part of the team that was going to rid the world of wars, famines - misery. We were going to drag man out of the mud with our superior "technology". The indoctrination created my tunnel-vision of this and shoved out the possibility that any other group (Red Cross, the local Christian missionaries, etc) had any real solutions. To be a true scientologist one must adopt a strong elitist attitude. Also arrogance is very helpful. "Our group is the only group doing anything decent for the world." Arrogance and elitism are, IMO, mandatory traits to be a fully-fledged active scientologist.
It is more than likely that there was latent arrogance & elitism lurking within me that pulled me into the group in the first place.

Scientologists don't do "humble" or "modest" particularly well. Not the one's I knew at least.
