Think of those test questions that give you 4 pictures and you are tasked to choose what does not belong: a chimp, gorilla, bonobo and a sea turtle.

That Sam Harris is named in the same group is a bit odd. He doesn't really fit with the others as an "entertainer" and from my limited knowledge of all of them appears to be the more focused or contained wrt subject matter.

Sam Harris was/is one of the “Four Horsemen” — a group of intellectuals and public figures in the mid to late aughts and early 2010s. The others were Richard Dawkins, Daniel Dennett, and Christopher Hitchens. They had their differences, but they mostly advocated for (classic) liberalism, increased science education, the separation of church and state, and warned against the nascent anti-intellectualism at the time. Having Sam Harris (or any of the other three) in the same group as Joe Rogan and his ilk is like putting a classic Ferrari in the parking lot of a used Yugo dealership.
