I don't, this guy seems to be an odd fool. He can't keep his hands off kids for one. From my experience of being a bad kid, people like this only get wound up this much when they're real assholes and shouldn't be teaching anyway. I was a piece of shit student, yeah, but i only messed with piece of shit teachers. And it was like that all over the show. If you tried this on a respected and well liked teacher other kids will step in and stop it, and you see this happen in lots of other videos where someone puts hands on a teacher and 10 people run in and stop it. i think all of this is more of a larger generational shift where the new generations have a lot less respect for authority, but still have a general sense of respect based less on power and more on actually treating people well. In the 70s you could be an asshole and it worked, beating your kids was still normal, that discipline could be enforced physically. This dude is a relic of a by gone era where you can still fix a kid by hitting them, and he isn't able to cope or change with the new world. Feel free to disagree but thats my perspective.
