Reply To: Different levels of religious observance (frumkeit)

L’maaisa, it is much worse than pritzas geder for someone from a community that holds non-Cholov Yisroel is pure Cholov Akum, and hence utterly assur no differently than milk from North Korea, such as virtually the entire Chasidish velt (i.e. commonsaychel with his Rebbishe stock) and others (i.e. Oberlanders), than it would be to eat non-glatt by someone from the MO world (such as DaMoshe, even if he tries to taaina that Hashem made available the wonderful foods from Hebrew National) and various other communities. Since even by the latter we acknowledge that m’ikur hadin non-glatt is kosher whereas by the former they pasken that what others refer to as Cholov Stam is actually Cholov Akum mamish.
