Quite a generous interpretation of a guy who is actively destroying the public health system, and whose idea of a family vacation includes a bloody whale head on the roof of the car.
Next time you take a step outside, look around. Obesity, skyrocketing rates of all forms of mental illness (one of the most relevant being autism), rapidly declining IQs [1], plummeting testosterone levels (even for people in otherwise good physical shape), and much more.
Why? Nobody knows. So the answer is most likely that we're doing what we've endlessly done countless times dating back to at least the era of the Roman Empire, and are accidentally poisoning ourselves with something (or some things) that we are convinced is completely safe. I'm not saying that Kennedy is right, but I am saying that "we" are wrong. And so walking down a different path on occasion is not only okay, but a very good idea.
