Pesach -Preserving the Sanctity of the Haggadah – The Rebbe on Additions

From Rulings and insights from the Lubavitcher Rebbe - Rabbi Chaim Wolosow by R Chaim Wolosow.

The Rebbe strongly objects to inserting Holocaust content into the Haggadah. Its precise, sacred text must not be altered, especially in ways that disturb the spirit of joy and freedom. Such painful subjects require their own proper time, not the Seder. https://www.torahrecordings.com/shulchan_menachem/orach_chayim/246_002
