“I am not sure who your Rabbi is, since you do not name him”
He is smart enough to avoid publicity, unlike me. (Hmmm….maybe I should follow him more closely on that one.) But he has surprised The Rav’s grandchildren, including Rav Twersky, with some of the things he heard directly from The Rav.
“not in the derech of R Soloveitchik”
Rabbi Hershel Schachter does not always follow Rav Soloveitchik either. Nothing wrong with that. My rav asks shilahs of Rav Schachter! And in any case, Rabbi Lookstein is also recognized as one of the prime talmidim of Rav Soloveitchik, who praised the Ramaz School effusively (and himself ran with his wife and daughter a similar school in Massachusetts, the Maimonides school).
“I fail to understand how Harcsztark became a posek”
He became a posek when he was hired by the SAR board. They put him in charge.
You don’t like that? Don’t send your kids to SAR!
