RebE, indeed, my hevruta and I were once kicked out of the class specifically fir that. As the rebbe said in front of the class, our misbehaving didn’t affect our learning but affected others who were copying us.. this tochacha actually worked
.. still, this contradicts numerous stories of gedolim personally protecting such kids. Maybe there are other gedolim who hold differently, then please bring the sources.
I once talked with a school administrator about challenging kids. He shared with me how he visited r Kanevsky with a shailoh about his child. I asked him then who is the school asking such shailohs about expelling kids and he didn’t have a ready answer. Do you know who is your school asking shailos of?
