Your willingness to paint something you dislike as "dangerous" "harm", and your reduction to binary opposites with no discussion of nuance speaks to an authoritarian, "Witch hunt" mindset.
This suggests you are uniquely incapable of dealing with the issues in a scientific or rational way, making you equally unqualified to judge anybody.
I think the attitude displayed in your comment, is what's dangerous. I'm not saying JFK is "not dangerous", but not in the way you think, perhaps. And I'm not going to reduce people, or issues, to simplistic moral fables. Such a flawed model can never represent reality, so anyone wielding it can neither be said to be in touch with reality, nor capable of deciding anything that matters.
But the willingness to hate, is a dangerous thing. Think on it! Hahaha :)
Plenty can be said about Newton, but his belief in alchemy given the time was far more reasonable than RFKjr's insistence on continuing to do harm by pushing those false claims.
