What? I was describing how cults/high-control groups react to criticism. I wasn't trying to assess how accurate their beliefs are. Cults rely on having some beliefs which reasonable people might agree with. Those are the beliefs they present to the public. Cult literature often sounds plausible or benign even if it's not factually accurate.

Before there was greater awareness of what cults are and how they work, it wasn't uncommon for early press about cult groups to conclude that while some of the cult's beliefs were strange, they had good values and were doing good things for their communities so they were probably harmless. It was only later that stories begin to emerge about the extreme levels of control that cults were exercising over their members, how that control led to the exploitation and abuse of members, and how limited and transactional their "good works" were.

If a group with that model of control and exploitation claimed to have access to a source of genuinely new and scientifically significant knowledge, they are the worst people to be in control of it, because: a) Cults keep back the larger part of their beliefs from the public in order to extract as much in money, volunteer time and other resources from their members. If a cult did have a direct line to Xenu, it would be directly in their interests to strictly limit how much other people can know about Xenu without paying exorbitant fees and submitting to cult authority. b) Cults are run by people whose ethics are compromised. Cult leaders believe above all else in their right to power and/or wealth and everything else including the health and safety of others comes second. They bully and indoctrinate their subordinates until cult members believe that there is no good and bad so much as there are things that are good for the cult and things that are bad for the cult. If people with such compromised ethics gain access to Xenu's special information (why are we assuming Xenu will be wise and helpful anyway? In Scientology mythos, Xenu is evil. And also dead.) they will use it to improve the position of the cult and impose their beliefs on as many people as possible. c) due to the above mentioned, it will be extremely difficult for non-members to assess the accuracy of information provided by the cult.

while it's true that if my dick had wings, it would be a magical flying unicorn pony, so far this hasn't been shown to be the case at all, so i'm not putting effort into the hypothetical
