Csar: Where did he argue? (Also, there is a ton to say on this, both against the P’sak and against everyone here’s clear misunderstanding of it.)
Loyal Jew: Your common sense doesn’t dictate Halachah. Baruch Hashem He gave us a Halachic system to determine Halachah from actual sources, not from whatever “common sense” everyone has as to what they feel the Halachah should be.
Also, mods, how is that link in the OP allowed? It’s not a link to Hebrewbooks. At least, not for me.
