TLIK -“There is a place for a potch”
The only time that I Know it’s Ok, is when it’s a last Resort.
Eg. – Kid hitting another kid & won’t Stop.
Running across a street, despite trying to hold him/her back.
The ones that say it’s Ok once in awhile are Wrong. (Except with those or very similar cases – I just posted.)
Times have changed & the Gedolim say those Chazals that say Corporal Punishment is Ok – doesn’t Apply nowadays!
The ones that Keep harping on that, are Megaleh Ponim She’lo K’halacha!
