Kindly cool it, newbee. A bit of respect for the Godolei Olam, Kedoshim uTehorim of the past.
Their psak was divrei Elokim Chaim. Contrary to your (and many other’s) belief, their ruling was not a haphazard saying, byword or assumption. They knew the gravity of their words, gave precise, directed rulings. And they knew what they were talking about. I would think it’s utter chutzpa to address these Gedolim in such a manner.
FYI, you claim that your ancestor came here was frum and etc. and here you are. Woopie Doo. How many thousands of other were not. Do you know the figure of the masses of Jews that came in that era, and prior to it, only to be TOTALLY LOST? Them, their children etc? OK? And those that were murdered, did so keeping the Torah, so they did not have a misas neshamah r”l. Open a sefer, kindly, (that’s a Jewish book) and read about ???? ??????? ???? ?? ??????.
Yes, those that were nebach killed, with Shma on their lips, were a lot luckier than those that came here to abandon their Jewishness.
