it's only because you already want to believe what they're telling you. It cites 3 different surveys to support its claims, but curiously links to none of them. Doesn't that seem a little suspicious to you? It also seems hardly coincidental the number of prominent links on that site peddling Hydroxychloroquine.
And notably, it doesn't show that how any countries have gone "all in".
Again, as I said there may very well be some therapeutic benefit to Hydroxychloroquine's use, but let's please temper this all, there are way too many unknowns right now to sink into the sort of hyperbole our president and others are engaging in.
