I would be interested in seeing some citations to back up that claim. The famous Jonestown incident was a case of people having left everything they knew, relocated to an isolated place in a different country, etc. And even then, some members of the cult were
forced to drink the poisoned kool-aid and some drank it
not knowing it was poisoned.
Residents of the commune later committed suicide by drinking a flavored beverage laced with potassium cyanide; some were forced to drink it, some (such as small children) drank it unknowingly.

I have a longstanding interest in social psychology and the way a cult generally arranges to control people is to cut them off financially, socially, etc. This is the same way that abusive husbands typically treat their abused wives. One study sought to identify character traits that made abused women more likely to kill their abusive husband and could not do so. Instead, they found that the women who murdered their abusive husbands were the most isolated, the most abused, the most painted into a corner. In short, they were women who found themselves with no other way out.
I suppose if you work for the man or are enthralled by his billions or some such, that's going to hold sway for some people. But I have trouble comparing his Twitter debacle to what cults do.
Anyway, just rambling on. Not actually interested in discussing this Twitter mess that I am mostly trying to avoid discussing in spite of the entire world seeming to discuss nothing else.
But if you have some citations to back up your social psychology related statement, I would be interested in seeing those as it's an area of interest of mine.
