I think you are being too harsh, but generally on the right track. There is a valuable lesson to be learned about civility, but the place to start is inside the classroom, between teacher and student, and between the students. In the teacher's mind, the children are bad. But the real situation is that the students are sick. This is very much like the change starting to come with regards to treating drugs as a health issue, not a criminal one.
The right place to start is with equanimity and respect for society. Equanimity because interacting with people in real life is sometimes rather painful, and you can't take things back. Respect for society is similar to respect for the parents: this crazy, evil, dysfunctional society sort-of raised you (and your parents). Society is responsible for providing you with literally everything you know - even the basis for the views you have that loath society. This requires a kind of humility that is very difficult to impart. Usually it comes (if it comes) after a person has been self-sufficient and recognizes the very real trade-offs they might have to make in order to achieve even a fraction of their goals (which is precisely what happened to their parents, most likely).
Of course, all of this is far too much to ask of a single class. He sort of jumped at the students from one, relatively random direction (there are lots of other problems that weakness and disrespect engender, like lack of self-control, depression, etc) and certainly there are not shortage of well-meaning people honing in on some narrow error mode that is really a symptom of something much deeper that takes years of effort to overcome. In any event, a teacher who grows so easily angry when his students demonstrate ignorance of the very thing he's trying to teach might consider the real possibility that he's not fit to be teaching.
