I used to wonder why leftist speakers are so “popular” at colleges. I know of two reasons. One is after telling the crowd what they want to hear, they also keep the students and graduates separation from reality going. The second reason is that they’re available. A non leftist speaker who would give them worthwhile advice is probably hard to get being that they’re usually doing something important.
After reading her speech I also came to the conclusion that the people who select the speakers want to make sure that the students feel that they’re smarter than the speaker.
