You're whisling past something. I fear not Tom Cruise, but I do think Islam is a threat.
Fear not Tom Cruise. Fear the countless masses who assign him instant credibility for pretending to be important on the silver screen. That's his function within the movement... that and his money (which is being used to buy America by the county).
You're seriously underestimating this cult. They just stood up to the Governor of Florida, the Congress and the President of the United States. And they didn't flinch. And they got away with outright barbarism in front of the eyes of the world... with overwhelming support from the American public.
I used to dismiss them as a whacko celebrity cult, too. Not anymore. They're a force that is going to have to be confronted.
Islam didn't legally starve and dehydrate a disabled woman inside U.S. borders. They are both a threat, but Scientology is a much quieter one.
