The leftism that's driven people to the right isn't reducible to a few people in academia. It's the result of a cultural atmosphere that has demonized conservative values. This, by and large, has not happened in the classroom; it's happened because social media has intercepted a generation of humanities-educated young professionals (or young unprofessionals, whatever) who often misuse or misapply the tools given to them. They have all the catch-phrases and all the hot-button topics and none of the critical thinking skills; after all, it's easy when you can imitate a discourse. It's much harder to actually grasp the dynamics and internal logic of a discourse.
If we need to wake up, it's to how we've failed (not me personally, of course, as I wasn't teaching then) to properly communicate the tools and concepts we teach. To be entirely honest, we don't want to teach opinions or perspectives on explicit political topics. We want to teach critical thinking skills that allow people to assess political issues and come to their own conclusions.
People like Henry Louis Gates feel the need to make these clarifications because we live in an era in which a) most conservatives see the academy as something misguided, inbred, and dangerous, and b) most incoming students have been raised in a social media environment that has taught them a nonintellectual, firebrand version of academic thought. They come in with all the buzzwords and think they're good to go, hence the Berkeley protests shutting down conservative visitors.
What really frustrates me is that this isn't denial at all! If anything, most academics are disappointed and disturbed by the current political climate and their role in it.
Well that's far too vague. I could 100% agree and mean something 100% different than how that would be generally understood.
As I said, it was in the Q&A. He didn't mention psychology at all, I'm speculating.
