Missouri opens up kid-friendly BDSM dungeons at taxpayer expense

You wouldn’t think it would have to be a full training thing to tell them to use a moderate force to rap their knuckles or whatever, but this a profession where the teachers had to be explicitly legislated away from showing pornography to primary students. So yes probably worth a class to understand why corporal punishment is an effective tool, what situations to apply it, and how to do it properly.

I'm not sure what you mean by "beating a kid properly." If you're asking if I think physical punishment is ever appropriate, the answer is no. If you're asking if I think teachers should be allowed to physically punish students, the answer is also no. There is never an excuse for hitting a child, and anyone who thinks otherwise is not fit to be a teacher.
