she was one of the first people to give the antivaxx movement a platform and never bothered to decry it and then everyone started paying attention to it and even believing it because she is oprah
she also promoted a book called “the secret” which claimed that trying and wanting hard enough to be cured would cure someone. one of her viewers wrote to oprah saying she saw that show and stopped treatment for cancer, and instead uses a holistic “doctor”. her name was kim tinkham. she and the holistic “doctor” were invited on the show talking about how he cured her cancer and how his alkaline diet could cure cancer and so many other health problems, again providing a platform for deadly awful shitty anti-medicine.
kim died 3 years later of cancer. and who knows how many other people tried to quit cancer treatment or otherwise died because of some shit oprah promoted on her show
