Um what? Are you kidding? You’re insinuating that the chofetz chaim didn’t follow b’feirush halacha?
There is a well known story of a bocher who was caught smoking in the yeshiva on Shabbos. He was called in the Chofetz Chaim and what do you think the Chofetz Chaim did? Do you think he yelled at him, YOU KOIFER , you are being kicked out of the yeshiva and its assur to drink wine you touched and you are no longer part of the minyan?
No the chofetz chaim didnt say a word, He just cried into the bochers hands and said Shabbos and cried some more and said shabbos and the bocher got the message
