I've found that the majority of kids pretty much believe what their parents teach them. Republican parent - republican kid; democrat parent - democrat kid. Same with religion. Kids believe it all and its all they know because they are separated from worldly kids as much as possible.
But, once they get older and actually get questions from people that they can't answer or comments from people that make them think then maybe they'll wake up and realize it's a cult or at least a high control group.
