Kosher Ham and I were quoting a guest post writen by Paul Shaviv who is the head of RAMAZ.
Read it again, Paul spoke to Rabbi Pruzansky regarding some of the data and methods used in the study and Rabbi Pruzansky admitted that he was relying on an oral report.
Whatever issues you have with HM are not relevant here as this was a guest post by a third party.
I’m sure that wherever these “numbers” are somewhat applicable it will be addressed, my comment however was more about how this might creep into a drasha as a “look how much better we are then them” type message.
But feel free to dismiss me for my uber sarcastic comments and my insightful barbs and splashes of reality.
