Yes!
Yes, but only for discipline. Problem is, teachers are all too young and liberal to even know how and why that works. If you were never disciplined as a child then as an adult you wouldn't be able to execute a spanking that be effective in its true intentions.
Yes bring back corporal punishment, we got it from coach in school, most of turned out good, this gen has no fear
Yes.
Absolutely no
No, it should be administered by the one person, the principal. When I was young they and coaches did that. Although it was in elementary school, it was never used. More of a scare tactic. Used Jr high and up. NOW, parents should opt out or should have a witness/parent.
Never… never, never,never.
