You are getting the argument wrong. There is nearly universal agreement that HCQ is a covid inhibitor. The issue of concern that has caused the backlash is the safety for individuals with pre-existing heart problems.
That’s a BS argument. A slight arrhythmia is not that serious in the vast majority of cases. However, that is why you should seek a doctor to make the determination. In fact, you can only get it with a doctor’s prescription. But the argument really is that Fauci says it is only anecdotal, but this study dispels that argument.
