Living here where they swarm I naturally come in contact with plenty of Scientologists, have done work for one of their business arms and have some as individual clients.

They tend to be rather screwed up people, but perhaps no more screwed up than
before they joined Scientology. Their word processor files are predominently letters to Scientology authorities complaining about each other.

Unfortunately it is a religion lawyers find attractive so they have plenty of lawyers and tend to use them. That is the primary real danger of Scientology.
