The way that occultists all claim that all of the other occultists are clueless posers is one of the things that makes the whole lot look rather silly.
The OECD suggests [1] that there are about three nurses for every doctor. Complain about doctors as much as you like, but most nurses have lots of useful and relevant practical experience.
(I think most doctors are probably fine. But I don't need to win that argument to deny the 90% claim.)
