The article doesn't denounce Tyson so much as N word culture. It does say that just because you attend comic con doesn't make you a bonafide intellectual. I don't read comic books or go to comic-con conventions. They hate the 60's Batman TV series, I think it's hilarious. Cooke correctly criticizes those argue in favor of climate change while not really understanding the theory. This he claims is a result of the wedding of Hollywood, science, and politics.
The article did not mention climate change or evolution but it did talk about how N word culture shuns researchers Cooke admires such as Charles Murray (author of the Bell Curve which argues for a racial hierarchy of intelligence) and anti transsexual Paul McHugh. Cooke also claimed that there was conclusive evidence that the government programs Medicaid and Head Start do not work (I've read considerable evidence to the contrary).
With all of this complaining about the supposed snobbery of those who engage in intellectual pursuits, I'm reminded of the founder of The National Review, William F. Buckley who debated Noam Chomsky in this clip about US foreign policy, Both men engage in high sounding words but Chomsky speaks in opposition to US power while Buckley is in favor of the war in Vietnam. Snobbery is only a problem when you're on the short end.
Understanding of complex phenomenon is aided by presenting scientific principles in novel ways as the series Cosmos did in 1980 and in 2014. The science was sound but it did not jive with what the right wanted to hear at least with the 2014 version. I don't know if the National Review criticized Carl Sagan and the original Cosmos but SCTV did a pretty good spoof of both of them in The Battle of the PBS stars.
