“the discussion here was to interrupt set times that yeahivos learn to honor soldiers.”
didnt realize
I was the one who first mentioned “a moment of silence ” (as an idea that I would understand, I don’t understand the OP)
Joseph Kidarko bakodesh said “It isn’t worth giving up even 60 seconds of Limud HaTorah for this purpose, even for a “moment of silence”.” Unclear why he assumed the “moment” had to come from Talmud Torah.
a moment can come from Lunch, recess, typing in the coffee room .
Your “General rule” is cute but Indicate a lack of familiarity with Yeshivos. Time is taken from talmud Torah all the time, for tehilim , a Rosh Chodesh mesiba, Lag Baomer mesiba, various zichronos for the Kedoshim ( I remember well the Kaliver Rebbe Z”l speaking in my elementry school, we all went out to greet him and he taught us his song Shema Yisroel, that I can still hear)
Now, to be clear I am not suggesting that the topic at hand is remotly as important as any of those interruptions to learning. but then again, nor did I suggest or condone interrupting learning in the first place.
