The right wing has been obsessed with defending quackery for decades. They have an inherent mistrust of anyone that knows things beyond their understanding.

The question is: who would profit from Americans dying for preventable reasons?

Is those racist assholes were against e.g. vaccinations for non-whites in order to eliminate them, it would made “sense”, at least for their racist minds.

But they are trying to eliminate everyone, including themselves. It makes no sense, not even for them.
