First, MIT isn't Ivy League, which I don't just mean as a pedantic point about a football league - the Ivy League are all liberal arts schools. MIT is a technology school. It makes sense that there are institutions whose purpose is to provide a platform to any speaker. It does not make sense that every institution should do that. That's my complaint - this author who claim to care that distinct points of view are well-represented has rounded off a specific school into Generic University With The Same Classical Liberal Worldview As Every Other University.
Two, please tell me how many times in the history of your Ivy League school, since its founding until your attendance, they invited an African-American speaker.
When I was a student many many years ago, it was such an accepted truism, that it didn't even need to be mentioned.
