As I said at the beginning, all conspiracy theories are associated with grift. The grift might not be what gets them started, but it is definitely a prominent component of any conspiracy theory as it matures. Moreover, as I pointed out before,
science denial is a form of conspiracy theory. It has to be, because believers need an explanation why “mainstream science” and “mainstream media” reject their conspiracy theory. Naturally, it has to be a tyrannical conspiracy to “suppress” their ideas.
Ivermectin as a “cure” (or at least a highly effective treatment) for COVID-19 is basically science denial. It is still possible that science will show ivermectin to be effective against COVID-19, but from my perspective that outcome is looking less and less likely. Thus, not surprisingly, the promotion of ivermectin requires denying the inconvenient science, with all the techniques of denial used by denialists ranging from creationists, to antivaxxers, to cancer quacks, to climate science deniers being marshaled against disconfirming science. Because all science denial includes a conspiracy theory, we should therefore not be surprised that ivermectin advocates have not only embraced conspiracy theories about the “suppression” of their favored COVID-19 cure, but have gone beyond that to go even bigger on the conspiracy mongering to portray any effort to combat disinformation as a grand conspiracy to suppress The Truth about…everything.
