If the West had always been this risk averse with respect to science and technology, we wouldn't have gone to space let alone the Moon. We wouldn't have antibiotics and we probably wouldn't even have flight. So tell me how to restore America's healthy level of risk tolerance? Because taking medical advice from online pundits is incredibly risky and yet it's seen as safer than trusting science by a disturbingly large minority. And that's just one example of how badly we gauge risk.
And to be fair, I have the same viewpoint about the irrational fear of nuclear power.
