Greg Gutfeld hates people who are "cool."
Correct me if I'm wrong, but it's not 1977 and nobody uses that term anymore in any meaningful sense. It's an outdated term that no longer has cachet with younger people. So, what's the point of writing a book when you can't even understand the culture? Are cool people only the ones who oppose Gutfeld's conservative agenda?
Nobody likes hipsters but who's losing sleep over it? Greg Gutfeld, apparently. This is the manifestation of conservative anti-intellectualism. Knowing things means you are cool and cool is the enemy of the conservative book troll.
