Acceptable belief vs. True belief are independent. There are some beliefs that are acceptable (Jesus) and others that are not (Zeus, Scientology). They are equally likely depending on your perspective.

The Internet has enabled people that think they have found a true belief that is unacceptable to find each other more easily than ever before. The creation of these micro belief systems is one of the most interesting aspects of the Internet. Lots of these on Reddit as an example.
