Rabbi Yair Hoffman wrote an obituary for Margulies in Vos Iz Neias, the NY based Haredi news website: “HaGaon HaRav Chananya Yom Tov Lipa Margulies ob”m Passes Away.”
It includes this gem: “Not everything, however, was perfect or ideal. The Avos themselves had, at times, made what appear to be miscalculations that could have chas v’shalom jeopardized the future continuity of Klal Yisroel. Avrohom Avinu had to be told to listen to the wise advice of Sara Imeinu in ensuring that Yishmael not be kept around Yitzchok Avinu… Sometimes, other Gedolim perceive the true depth of such dangers – whereas others do not. Rav Avigdor Miller zt”l had argued with Rabbi Margulis on such a matter.”
BTW, it wasn’t just Avigdor Miller who described Kolko’s abuse to Margulies, It also included Rav Avrohom Pam, RY at Torah Vodaas, and many others including many children, parents, and askanim. R. Hoffman collapses a story of decades of protection into a comparison of Avrohom Avinu and Lipa the Rasha. If he wanted to draw comparisons from Bereishis he should have gone to Sodom. Compared to Lipa, even Lot looks better. At least he tried to protect those he thought were adult males from sexual assault. A plain pshat reading of torah suggests to me that if Lipa had been in Sodom he would have been condemned with its other residents. I mean, doesn’t a rosh yeshiva have at least as much responsibility to protect children as a simple resident’s responsibility to protect visitors.
