More like what an idiot, a 5th grader could tell you quinine has been used as a drug for the last 4 centuries, that it used to be used in Rome in the 1600's to treat malaria, and that yet again the link you provided proves what people are trying to tell you, that you shouldn't just take random drugs without knowing what the hell you're doing and what their side effects are, I mean you've literally posted a link to an article that goes to show what the possible consequences of doing that are and about a guy who speaks from experience.
Person with two brain cells: Don't take random drugs in the hope they'll make you better without understanding if they will.
Cuomo: I'm going to take a random drug in the hope they'll make me better without understanding if they will.
Trump: I'm going to take a random drug in the hope they'll make me better without understanding if they will.
Cuomo: Don't do that, when i did that it made me worse.
McEnany: Cumo is a hypocrite because he took a random drug in the hope it would make him better and it made him sick so he's in no place to advise Trump on the effects of taking random drug in the hope they'll make things better without understanding if they will.
What someone does in private is entirely up to them (within the law), however Trump decided to make what he does in private public when he told the world, if that was you or I it wouldn't matter much as we don't have audiences in the billions and have limited influence, however that's not the case for the POTUS, as much as some people may not like it words matter and for someone of the POTUS' power and influence they matter a great deal.
