The entitlement of this stuff befuddles me. Charles Murray is totally and completely discredited. It is not fake news. I do not know a single, legit political scientist who thinks his work has any merit whatsoever. And yet he’s this darling of the right, which is weird because there are actual conservatives in political science, especially international relations, you could invite and actually learn something.
The “we’re testing free speech on campus” thing is a bit rich. You don’t need to test free speech. He’s walking around, not in jail, no matter what he writes. That’s the actual test of free speech, not whether he’s entitled to a big venue or tons of university resources.
