I think what cemented my resolve on the topic was reading the rickross forum reactions. They were so over-the-top group-thinky and WRONG that I suddenly felt I had to start defending cryonics from these weirdos.

Banning Mark Plus from commenting and explicitly restricting the topic to "ways in which cryonics is a cult" was probably what really flipped my bozo bit on them. That was also probably around the time I read this.

Now that I know the context of their experience with scientology I'm a bit more sympathetic to how they could be honestly wrong. I mean, they are thinking crazy, but something real happened to put them in crazy mode.
