Q. When a bachur sees a sign put up in a yeshiva that is not appropriate for a Makom Torah and it is not appropriate for a ben torah to have written such a thing, may one immediately rip it down even though it is not his?
A. It may make better sense to avoid a machlokes, to ask the Mashgiach or one of the Rebbes to remove it, if they so decide.
Horav Shlomo Miller’s Shlit’a opinion is similar.
