Why?
Why do I dislike Neil DeGrasse Tyson? For the same reasons that I dislike Bill Nye the Pseudoscience Guy: Pompous poseur, politicization of science, intellectual vacuity. What’s not to dislike. I actually liked Tyson when he was just the curator of New York’s Hayden Planetarium, and a science popularizer.
Why am I skeptical: there are a lot of loose cannon on the shifting deck of any graduate school, and occasionally one goes off.
