Insight On A Chabad Minhag - To Klop Or Not To Klop?
A Lubavitcher friend of mine pointed out that the Chabad minhag to only make noise at Haman's name where he has a title (e.x. Haman ha'agagi) was the minhag in Lithuania and White Russia. Interestingly, he also pointed out that the Rebbe said in a sicha that people should not be stopped from making noise at other mentions of Haman's name if they want to.
A footnote in Sefer HaMinhagim also indicates that the Friediker Rebbe did such:
"The compiler of the Siddur Yaavetz (R. Yaakov Emden) records that his father (the Chacham Zvi) used to stamp with his feet and clap with his shoes when Haman's name was mentioned; and I saw my revered father-in-law, the Rebbe, do likewise (in contrast to the views of the Acharonim cited in Sdei Chemed, loc. cit., sec. 10)."
Does anyone know the basis of the minhag in Lithuania and White Russia not to klop at every mention of Haman's name?
