Don't give short shrift to one of Scientology's most defining qualities - its arrogance - 2017-11-27
You can't really begin to understand why it's so difficult for Scientologists to rejoin the outside world unless you keep in mind that throughout their time in the church, they've had it pounded into their heads that Scientologists are superior to the rest of us, who are considered "degraded beings."
Founder L. Ron Hubbard promised his followers that his ideas would literally transform them into a new, superior species which he called homo novi, or "new man." And along with that came a sneering disregard for what he called "wogs," Hubbard's word for non-Scientologists which has racist origins in British slang.
The promise of "evolving" to a new sort of creature is a common feature of New Age charlatanism, of course, but Scientology takes it to the extreme. Not only do Scientologists believe that they go to a higher, superhuman state as "Operating Thetans," but they are led to believe they will eventually reach a godlike state giving them the power to crush whole planets between their thumb and forefinger.
