This is a trend I've observed in proponents of New Age alternative "medicine", way before COVID. They can simultaneously believe that Western medicine is "unproven" or a "hoax", and that doctors are "untrustworthy" and "big pharma" wants you to buy unproven stuff, and no amount of qualifications will convince them. Yet they have no trouble believing Bach flower remedies will cure anything, they follow homeopathy religiously, and it's enough evidence that some healer is the real deal because they heard someone at the grocery store say so and she seemed like such a nice person. Or some TV celebrity said so, and why would he lie?
