Mods-Hilarious!
DY-For the purposes of this discussion, meikar hadin means not bshas hadchak.
Where in the Igros Moshe does Rav Moshe tz”l say only bshas hadchak? YD 4:5 is a specific case. That is how Rabbi Daniel Eidensohn reads the teshuva. (See the Yad Moshe) So now you are left with a teshuva outside the Igros. That teshuva does not say “bshas hadchak” just “not proper” and one “needs” to get chalav stam. Now, I am not 100% clear on what Rav Dovid shlit”a says his father’s opinion is. But he clearly does not say “bshas hadchak”.
