Why does Facebook get to tell me what's false and not? I'm an adult, I can handle it and research validity myself. Why is it making decisions to what I can and can't see? It's like they're the thought police. Why aren't they removing all pseudoscience in this case? Why not astrology, why not psychics, why not tarot card readers, why not people selling weight loss drugs, why not people showing videos of 737's recovering from a barrel roll on short final, why not homeopathy, hell why not literally all religion?
