OK.
sorry if i wasnt clear.
again, I have seen the oleh correct the baal koreh many times.
I myself have been in both position. (served as corrector or correctee).
I haven’t seen any hate caused by this event. I am shocked that you have and think it normal. I have seen annoyance, especially if the corrector is wrong (or the baal koreh thinks he is wrong).
but hate?!
