An interesting opening post and equally interesting responses . . .
One of the things I have learned in my now long life is that folks operate on and within their belief systems. They have accepted and/or believe certain "facts" based on experience and these data or propositions about life and its interrelationships then, thereafter, dictate their behavior.
The tragedy is that folks often are operating on these belief systems blindly and on automatic.
Because of the above, I would say that it is rather unhelpful to make a person wrong for his or her belief systems but instead to endeavor to have the person address and inspect the basis and data of the beliefs they hold. Some folks are capable of inspecting their beliefs and upgrading and correcting them based on new experience.
Making a person wrong for their honestly accepted or developed beliefs only leads to disharmony and is unhelpful . . . indeed, it is detrimental to all involved including the party projecting the wrongness on the other person.
I've had many belief systems and data I've used and operated on in my life that have had to be undone or upgraded. Even within the realm of the physical universe and in strict physical universe terms they had proven wrong. I well remember some from my champion athlete days: and example being that we believed we should take some glucose or honey/sugar to "get some energy into the system" before a race . . . . What a wrong answer that turned out to be! In retrospect, better, later developed science showed that the action actually crashed the energy production/utilization system of the body and that having the body burning lipids was a better way to go.
I write this because I see a lot of belief systems being expressed above. And, of course, they are based on individual experiences.
The only point I would make on that is: was a wholly correct believe developed from the experience? Partially correct? Partly false? Wholly false?
As I wrote in my book and on my radio show website: All of Life is a Learning Curve.
Personally, I like to re-evaluate and reconsider the lessons I have "learned" from yore and continue to inspect such for truthfulness and true workability in present time.
It is, I have found, unwise to be hung up in the past too fixedly.
The best thing people like Old Auditor (and yourself) could do is to take your particular version of the tech and promote it (and yourselves) in the open market ... and be completely upfront about what you are trying to do (improve everyone and make them think more like you do?).
You'll probably need to work extra hard to convince people that they need you (due to all the work being done to expose cultic thinking, lol) but you won't have to bother yourselves with the "bitter, the twisted" and the completely disinterested.
