The problem is, while he was not suggesting people do it, he was suggesting that it be researched. It is the dumbest idea and it has been researched, it's what many commit suicide with. There is zero need to research it as it is a total load of crap from a healing perspective (unless your healing is death).
And unlike normal people.. his supporters will try anything he even mentions, even if it is not within the context of what he meant. Take the hydroxychloroquine, the moment he brought it up, some jackass went out and took a bunch of similar sounding drugs and died... and then recent research shows that it actually increases the chance of death and has proved not to be effective at all based on the VA study.
Trump needs to keep his mouth shut, introduce whichever expert is going to talk, and get out of the fucking way, and stop injecting his "thought" process into the matter, because he is an idiot with zero redeeming qualities (and this has been his entire life, not just as president).
