@PNS You have to realize that teachers are the bottom rung of the academic ladder, before you get into the truly meaningly SJW drivel. Bottom line, they're not that smart. In that context, I question these videos. I think it's more like you have a few really dumb kids that are engaging with this moron. And the rest of the class is actually smarter than them, hence they have no respect for them. Hence, they don't participate and check out. I think that's closer to reality.
