DY: I have been told, on more than one occasion, that because I eat Chalav Stam I have no Ne’emanus on Kashrus because “Kol HeChashud Al HaDavar”. They wouldn’t eat meat in my house.
Also, I once heard a great quote from a Rosh Yeshiva ZT”L of mine. He said that when he was growing up, it was a Mechze K’yuhara to follow every “Ba’al Nefesh Yachmir”. He said a Ba’al Nefesh meant R’ Chaim Ozer or the Chafetz Chaim. Nowadays every guy who opens a Mishnah B’rurah suddenly thinks they’re a Ba’al Nefesh.
