Hello99,
I believe the OU is probably being meikil with some sort of tziruf, as R’ Moshe does. I will bl”n try to ask R’ Belsky; I hope to see him at a chasunah in a few weeks.
You are making the m”S worse than the akum by attributing to the Sha”ch the possibility that he was menasech to A”Z. The Sha”ch, in fact was not reffering to a m”S at all so no inference can be made from his words.
The posek I referred to was not thrilled that the hechsheirim are meikil.
I would phrase it differently than you; many poskim are machmir, but there are grounds to be meikil.
Re: Hana’ah Mimaaseh Akum –
Are the gedarim for hana’ah from a goy the same as from a Yid?
Also, since according to the shittos that there’s no bishul after mB”D it would be a shvus d’shvus b’makom mitzvah, could we not at least be matir b’dieved?
