its terribly wrong
the teacher certainly should be corrected
fired? maybe
sometimes a teacher can be so frustrated, feeling she has no way whatsoever to control her class, that she acts out of desperation, and probably doesnt realize just then how wrong it is.
could be this itself is a sign of her incompetence and she should lose her job, but im not so sure
always this has to be done by someone who is sensitive to both the wronged and the wronging parties.
i know i have done some very foolish and harmful things and eventually came to see just how wrong i was but somehow at the time i just didnt see it.
of course the Binos Yisroel must be protected at all costs from harm.
hows that for wishy-washy?
