Here we go again...R' Moshe allowed the condition to be included in the Tenoim. That Teshuva has since been edited out of the new printing of the Igros Moshe. It is however still in the old version and R' Perr is still around to ask whether he got that psak.
So Reb Moshe's sons are choosing to hide this psak? Are you implying that not only are they hiding it, but that they're hiding it in order to torture women or to play fast and loose with halacha?
Why didn't Rav Moshe insist that couples should sign this agreement (which didn't really surface until several years after his passing)? Why is it that Rav Moshe's students have not taken on this mission, and instead left it to he the calling of a dying brand?
