DY: Honestly, I hate that response. “M’od M’od” doesn’t mean Ish Kol HaYashar B’einav to add whatever he wants and impose that on others. It means what the Shulchan Aruch says it means and is an additional level of practical advise to avoid a situation where you might stumble. It doesn’t mean that there’s no limit to the Chumros.
