No, doing my best, it is not at all crazy to suggest that medical researchers investigate some method of applying the power of disinfectants or UV light internally. And in fact with regard to UV light that is a very serious possibility. With disinfectants maybe not, but it’s a fair question to ask.
The LIE is that he ever suggested, or could have been understood to suggest, that people attempt the internal use of disinfectants, whether by injection or ingestion or any other method. He simply didn’t, and the hundreds of “reporters” who either insinuated or outright said that he had done so were deliberately lying. So were those who invented out of whole cloth a claim that his words have led to people actually doing so, thus causing an increase in calls to poison control. There was no such spike, and there is not a single known case of anyone trying it.
