First off, lets start out with what Scientology is:
The belief that an alien named Xenu came to the Earth 75 million years ago and dumped frozen space aliens into earth's volcano's which resulted in thetan alien souls that seek out to plague mankind forever.

..yeah, makes sense, right?

Scientology is a joke for a religion, it is a cult with a main goal being to extract as much money from the members as they can, in any ways possible. Now, I fully support what Anonymous is doing to Scientology, being friends with some members myself.

Scientology was created by a science fiction writer, 'nuff said. Since 2/10/08 (the day of the massive world-wide anonymous protest at churches of scientology) youtube has been systematically removing videos that would hit the top rated videos that had anything to do with anti-scientology, yet they would keep their ad about it on the pages. This is a huge violation of freedom of speech, and it has to be stopped.

My fingers are hurting now so when i can think of more stuff to add to this, I will post it.
