Medical mistakes while trying to help are different than drawing down on a black man for no other reason than he's a black man and shooting him dead. That is an egregious false equivalency.
But you should avoid all doctors, all the time, no matter the reason, especially if you have a crushing pain in your chest.

Your source here appears to be the website of Gary Null, Ph.D (not MD), who, from a brief check on that Other Wiki, "is hostile to evidence-based medicine and has accused the medical community of being in a cabal with the pharmaceutical industry to suppress novel treatments for economic gains. He has promoted a range of pseudo-scientific and ineffective alternative treatments, including ones for cancer... He is a HIV/AIDS denialist who believes nutritional deficiencies are the causative agents of all illnesses, and has accordingly promoted fringe, diet-based treatment regimes for curing AIDS and other illnesses. Null holds strong anti-vaccination views and rejects the scientific consensus on topics such as water fluoridation, genetically modified organisms, and electromagnetic fields." Short answer; he's making money scaring people away from real medicine and then selling them his books.

He's a chiropractor, which basically gives him exactly as much medical knowledge as me or my auto mechanic. My therapist also seems to believe in the world of "nutrition-based remedies", for the record, and as helpful as she is most of the time, I politely nod, say "Interesting", and change the subject when she starts explaining how your diet can fight covid better than a vaccine, for example.

So don't be offended if I politely say "Interesting" to whatever you reply.
