Do you think most people are capable of understanding why an expert could be wrong about gadolinium but right about vaccines? Medical advice is all seen as equivalent to most.
What is the equivalent when it comes to medical advice? Using vaccines as an example, one concern people have is the mercury content. The FDA, doctors, and drug manufacturers have said that the mercury is safe. The same doctors, manufacturers, and FDA has said that MRI contrast containing another heavy metal, gadolinium, is safe. It turns out that, no, it is not safe.
Given these facts, is it really surprising that people would turn away from the FDA and doctors just like people would turn away from a car manufacturer after receiving a lemon? While I personally trust the FDA, I can see the logic in the distrust after events like this.
And normally I wouldn’t really even bother acknowledging that that extreme stance exists. If you look hard enough you can find an extreme stance on anything. But the sheer percentage of the US population that has embraced an almost entirely skeptical/dismissive view of doctors and experts of any kind… it’s kind of horrifying
