Is Neil Tyson Getting It Wrong?

I just do not understand parts of modern academic culture or perhaps some modern academics. I think an academic engaging another academic and yes even on a personal blog if it's going to be out there and public should at least have some minimal level of courtesy. Academic culture is rapidly becoming what journalistic culture became some decades ago Politicized and then downright hostile to anyone who fails to meet the moral standard set by your side. Many of the kids today Who aspire to an intellectual life or a life in academia are already in mature social groups that navigate?
