Maybe Episcopalian was his upbringing, and is now just what he says. In that Scientology is markedly anti-psychiatry, and in a fanatical way, it's hardly something someone in his field could advertise.
Mathematically, ethically, I don't see how someone in the field could be recommending Narconon without having knowledge of their affiliation with that organization. How they could appear to anyone as not having those ties is just unfathomable to me, when it take 2 seconds to find out. He's either oblivious, or feigning oblivion, but while I'm not even sure which is worse, I heavily suspect the latter. It would be deeply concerning to me personally, to be taking advice from someone with that particular type of affiliation, and the many layers of complication that come with it.. especially based on some of the rather extreme history of the organization in question, which is hardly known for honesty and openness. And definitely steer clear of their gateway organizations..
How distressing. Sorry to hear it.. But I really don't think someone who doesn't have an affiliation with their parent organization, would be aligning themselves with Narconon when there are less controversial means of getting that kind of help.
