punkofnice, it's interesting that you mention the black and white thinking. Actually, even the fact that they force people to call something using a name they choose, those two things are actual signs of them being a harmful organization.
I have read a few books on spiritual abuse, and the black and white mentality is the number one manipulative tool used to spiritually and mentally abuse people.
Indeed, life is fragile, short and precious. It's very sad seeing it wasted in that nonsense, especially those who believe that they have to spend it all preparing for the next.
