�I realized lately that litvaks use the word kefira for anything not true, so when r shach said the rebbe is a k. He probably just meant he disagrees.
I also said it used to be common for people to call trouble maker kids sheigetz. I saw this in the book about the rogetchover, R chaim brisker called him a sheigetz.
So bh it�s nice to see that r shach wasn�t so seriously against the rebbe or chabad�
Whatever floats your boat sechel, now start a movement to have avi ezri in chabad houses (good luck with that)
