"I see disinfectant, where it knocks it [coronavirus] out in a minute—one minute—and is there a way we can do something like that by injection inside, or almost a cleaning. Because you see it [coronavirus] gets in the lungs and it does a tremendous number on the lungs, so it’d be interesting to check that."
There is nothing in his quote about taking taking the blood out first, he's talking about doing the cleaning inside the body. But lets assume for a brief moment that what you say is accurate, and someone is going to take out your blood and clean it with bleach.... THEN what? Now your blood is too toxic to put back in the body. Do you just kick back for a minimum of 24 hours while waiting for the chlorine to evaporate? It doesn't work if you only take out some of the blood, because it is constantly being mixed in your body, so you have to somehow completely drain a person without them dying. Now repeat that for 8 billion people, because this process would still do nothing to protect you from getting exposed again as soon as you walk in to a store.
You might also consider how covid would have gotten into the blood in the first place -- it entered the body through the lungs, and continues to grow there (which is why some many people had lung damage). So I guess while you're killing the patient by removing all their blood, you might as well take out the lungs and bleach them too? Who here can't hold their breath for 24+ hours? There's just no way any of this could ever be used as a serious treatment. Yeah covid deaths would drop overnight, but only because the "treatment" would have a 100% fatality rate.
Unfortunately there are people who really believe this way. The same people who think Trump is some sort of god and can do no wrong.
