As for the part about his responsibility, that part sounded like a no true scotsman argument (not sure about the spelling/capitalization of that, sorry). But also, couldn't someone argue that you, as a member of this community, have a similar responsibility to not put down Tyson? Aren't you contributing to the problem of hurting the perception of academics? Honestly, this is what got me to reply to your original comment. Seeing someone say Tyson was cheesy seemed light-hearted, but your comment felt like an attack on Tyson IMO
I don't see how his comments are more destructive than yours. But you are right, the question of whether his comments are destructive or not is subjective.
