When you say that people are lying about Trump suggesting that people inject disinfectant, what then do you make of his comment the next day admitting that he did deliberately say that (he is on video saying it was deliberate)? Saying others are lying about Trump saying this (and seemingly meaning it) is just dishonest. I get it that you like Trump, but to twist words and lie to paint him favorably is still lying. To say others are lying when they repeated what Trump said is just not right.
As to calling it a reasonable suggestion (i.e. to inject disinfectant), well I don’t think there is anything Trump could say that you would not consider reasonable. It is like a religious obsession. Most others, I think, were rolling their eyes quite hard when he said this.
