1. Universities have always been places where people challenge the establishment and the status quo. All these people like Bloomberg who are acting as if such challenges are a recent development in higher education are perpetuating, or creating, a myth. More than that, they are defending status quo and the establishment under the guise of calling out "intolerance" on college campuses. In other words, people like Bloomberg aren't concerned about intolerance in higher education - they just don't like it when people push back so they find a way to demonize or minimize their critics.
2. One of the central flaws in the recent criticism of university protests is that such criticism is most frequently rooted in the premise that the protesters haven't "considered" different opinions. This is a flawed premise because it does not acknowledge that many students have, indeed, considered different opinions, but that they have just chosen to reject them as inaccurate, immoral or inappropriate.
