Regarding the racist tirade that Rabbi Steven Pruzansky posted on his blog: That there is an Orthodox Jewish Father Coughlin, or three, given the size and conservative nature of the Orthodox movement, is not all that shocking. (“Decline and fall of the American empire,” Nov. 16.) That our rabbis could remain mute as one of their ranks publicly models behavior that our sages say will cost the perpetrator his or her share in the world to come is where the tragedy resides. Do our rabbis understand that their credibility as teachers, and the credibility of Orthodoxy as a halachah-based movement, is being tested? Do they feel the eyes of their students and congregants upon them?
