The same types of personalities which are attracted to the WTS's "anti-establishment/counter culture" RELIGIOUS BELIEFS are also attracted to the same "anti/counter" BELIEFS in other areas, such as MEDICAL TREATMENT.
Russell printed in the WT that medical doctors were modern-day equivalents of "Jannes and Jambres"- the Egyptian magic-practicing priests. In both Russell's and Rutherford's eras, "alternative" medical theories were continuously promoted in the WT and GA mags.
I have been associated with numerous congregations over the decades, and every single one had an Elder/Elderette who promoted and/or sold some type of "alternative" medical/health "system". Often, I was able to trace the origin of such back to a CO/COette. I believe that this "witchcraft" probably has roots all the way into Bethel.
I have seen genuinely ill JWs fall for this "shit", and suffer for years rther than get the adequate medical treatment they need. If there was some way to quantify this, I believe there has been as many people harmed by this "undetected" phenonenom as the WTS's blood policy.
