The NYT has a solid article, with some associated pictures and video, centered on a couple who left the Scientology organization after spending their whole lives up till then working their asses off for it. (Their parents were members, too, so that's how that were brought up.)
Hard to say where we should draw the line between respecting religious freedom and investigating what increasingly looks like a scam and an abusive, hyper-controlling cult. I mean, I know which way I lean viscerally, and I'm sure you know, too.
I guess I'll just leave it there, and let you read the article.
[Added] If you're wondering why my post title is in quotes, it's because that was the NYT's headline when I started composing this post. It is now "Defectors Say Church of Scientology Hides Abuse."
[Added2] Long-time Scientology watcher Tony Ortega has a good blog post on this NYT article.
