HaKatan: I am trying to impress upon you that “MO Shitos” don’t exist based on an “MO ideology”. Such a thing would be Apikorsus, the same as Paskening “Chareidi Shitos” or “Yeshivish Shitos” based off of a “Chareidi ideology” or “Yeshivish ideology” and not based off of Halachah and Mesorah would be Apikorsus. There is no such thing as “MO ideology”. I will concede to you that many consider themselves “MO” while they aren’t completely Shomer Halachah. That doesn’t make “MO” an ideology which will Passul any P’sak given by an “MO” Rabbi or Posek.
Just curious, what do you mean when you say “MO”?
