I mean there are medical textbooks that recommended injecting disinfectant for treating viruses, and there are no shortage of doctors who do it already in their practices. And if people are already doing it anyway, and as far as anyone can tell not immediately dying, then why shouldn't it be tested?
(the first talks about ozone, which is a disinfectant but fundamentally cannot be taken internally as it's a gas, and it's slightly toxic https://www.epa.gov/indoor-air-quality-iaq/ozone-generators-... ; the book mentions "Oxygen-Ozone therapy is a complementary approach less known than homeopathy and acupuncture" so that's obviously quackery as well)
Do you not see how it's ironic that you're calling other people quacks, in the context of literally lobbying against using empirical evidence to decide whether or not something is safe and effective?
You're engaging with someone who has endeavored to derail a discussion into partisan interpretations of Trump's statements. This after sidestepping logic in the original thread, bodes poorly for any further responses.
