Personally I find her very annoying. Listening to her voice is like nails on a chalkboard. She seems to think way too much of herself. Just don't like her. She acted like she was a big deal when she was a Scientologist, now she's proud of the fact that she figured out it was a cult. Like she was the first to do that.
As as far as "exposing" them, what rock have people been living under that they didn't know Scientology is a cult??? Their beliefs and tactics have been documented and publicized for decades.
