It is my understanding (perhaps naively) that many of the people who hold to those views, would not be much different than you or I in their beliefs. The main difference of course is that they go way too far and in the process add an element of legalism.
My experience with people who belong to Vision Forum, in many ways is one where I see a very dedicated group of people. In fact, up until recently I had not even heard of Vision Forum. However, talking to some of these people, they seemed very much in line with what I believe and I didn't see anything odd until I was made aware of their beliefs by talking to one of the elders.
