Ubiq – the discussion here was to interrupt set times that yeahivos learn to honor soldiers. That’s bitul Torah of tinokos shel beis rabban, which we do not do even to build the beis hamikdash.
The general rule is that we do not interrupt learning unless it is for a mitzvah that cannot be done by someone else
But if there’s a mitzvah that can be done by someone else (someone asks for a ride), then we don’t.
Many achronim say that when it’s bitul Torah derabim, that is, interrupting learning of many people, we don’t interrupt at all.
The above comments regarding the supposed importance of non-learning activities are irrelevant, and are only indicative of how necessary it is TO learn, so one does not misrepresent halacha in the way the posters here are. It’s ignorance, as these halachos are not hard to find. Perhaps if these posters ever had the geshmak of learning a ketzos or a reb chaim(not hearing about it in a digestible shiur, actually going through it yourself) they wouldn’t talk about learning that way.
