557: Using that kind of logic, you will completely repeal all the halachos of tochacha. You can say every baal aveira got a heter. Or every baal aveira won’t listen anyways, so forget the tochacha. IOW, never give it. That is simply wrongheaded. There is simply no difference as to whether to give someone tochacha for dressing pritzusdik than for being mechallel Shabbos.
The Torah and Halacha say we must give tochacha. We being all of us.
