Glosslip has a great article on the front organisations of Scientology. I think it's a timely reminder of the danger of religious organisations using "front" organisations to increase membership through subtle means. I see Christian schools as little different. But Scientology will always have a special place in my anti-religious thoughts.
I really recommend Piece of Blue Sky: Scientology, Dianetics and L.Ron Hubbard Exposed (US Amazon) which really goes into detail about the early history of the church and it's not all that glorious. But it's very, very interesting.
Scientology is not singularly evil, but it does serve as a singularly obvious example of the evils/excesses of religion.
