klug:
Your use of the posul ולא יזידון עוד is wrong. There is no trace in that posuk of the word or concept of chinuch, and it is your own concoction to put it there. I stated it earlier. Discipline produces compliance, not chinuch. It is incorrect and irresponsible to confuse them. That posuk was addressing compliance, and that was the dire need at that moment.
Everyone today recognizes that hitting is a tool in the arsenal. None of the contemporaries say it has no place. But if we allow it to be something it isn’t, we produce destruction, and it is impossible to say that this is a Torah value or direction. There is wide recognition, as per some of the quotes I shared, that today’s children are not the same ones as earlier generations. Applying the tools that were effective then that backfire now is foolish. I don’t think that shomer peso’im Hashem matters here.
My premise about what chinuch is stands tall, proud, and valid. Go back and study that posuk again.
