Just because something was done in the past doesnt mean it should be done now.
Paddling and Corporal punishment were practiced in the past.
Punishments as a dunce cap, Scarlet Letters etc
And yes I know people who were monsters in school punished for everything and are respectable members of society (and frum) and I know people who were wild, got similar punishments and LIVING with non-jews. I saw a story someone posted how she went to a rock concert in high school and the pricipal called her and all her friends and totally humilated them and she was so disgusted she is now with a “Surfer Boy”
You have to know the kids and what punishment to give.
