One of the first things I ever learned about Scientology is that they sue former followers and journalists. They are VERY litigious.
That’s when I CONCLUDED that they probably really are a cult with something to hide. That’s what happens when a cult tries to silence multiple sincere people. The cult cements the idea that it really is a cult in the minds of most people.
