2. On a rather related front: what do you think is the key differentiating factor that explains why humans (homo sapiens) have so devastatingly outstripped all ecological competitors?
My personal answer to question 2 explains why I have my doubts about all too rigidly accepting your moral thesis here. I mean, I accept and support the idea that honest debate can help surface tricky truths - and that in that context debate must be free, but not that all speech should be promoted unconditionally. That's harmful, and the only reason we're even talking about that is because as a society we've come to see the first amendment not merely as a tool to constrain an overly powerful, potentially abusive government, but as an axiom of patriotic identity. The first amendment is not perfect, and even if it were, it should not be applied blindly to every situation, nor should it replace all other social norms about honesty and truth.
But even if your perspective differs - I don't expect everyone to follow my lead, of couse - I don't think you're going to understand my reasoning without at least trying to understand and answer that question. In essence - your assertion that it's (implicitly unconditionally) "very healthy to have an enquiring mind" is backed by an assumption I do not share. I know that there are conditions here, and Rogan isn't satisfying those. And the heart of that disagreement is behind question 2.
Also, you don't think that having an enquiring mind is good? How do you justify that? And what is the assumption I made that you don't share?
