They also clearly are Americans who seem to think this is an American issue. Ivermectin use for COVID-19 is worldwide and isn't aconsequence of "rejecting American Institutions" but was a desperate attempt by caregivers to keep their patients alive. They think they are seeing a pattern - that it works. But humans are easily fooled and see patterns everywhere, so we need better data. In the meantime, those doctors will continue to use ivermectin, and an upcoming Oxford study will get us some better data.
Might I also add that the evidence in support of Remdesivir is much much weaker than the evidence in support of Ivermectin, that the WHO recommends against Remdesivir, and yet in America it's widely used and nobody is bitching about it. Hypocrisy.
