[ג' דחנוכה, ה'תש"ל]
באם
שלום וברכה!
אין חשש כלל וכלל – שעי"ז יבוא מי מהשומעים לעבור על הלאו
דאל
תפנו גו' (יד הל' ע"ז ב, ב: שלא לקרות כו'
כלל!
ושם ב, ג שיש בזה – קרוב לודאי – עוד לאו
דלא
תתורו גו').
ולהשתתף
בדיאַלאָגן וכו' וכיו"ב. באם יש איזה חשש – למה להכנס לכ"ז, ובפרט בענין שאפילו אביזרייהו כו' ובתקופתנו וכו'.
Gimel of Chanukah, 5730.
Shalom u'Vrachah!
There is absolutely no concern at all—that through this, any of the listeners will come to transgress the prohibition of "Al Tifnu..." (do not turn to [idols], see Hilchos Avodah Zarah 2:2: not to read etc. at all! And there in 2:3 it is almost certain there is also the prohibition of "Lo Taturu..."—do not stray after your hearts and eyes).
And to participate in dialogues, etc., and similar matters. If there is any concern—why get involved in this, especially regarding a matter where even its peripheral aspects are problematic, and particularly in our times.
Summary
The Rebbe teaches that one should avoid participating in dialogues or activities that may involve prohibited topics or associations, especially when even indirect involvement could be questionable. When in doubt about a potential transgression, it is best to refrain entirely.
