“”Nobody ever pushed a classroom full of Yeshiva students off the derech because a cell phone got past the door.”
Incorrect.”
No Joseph, correct. Provide the Yeshiva, and the year that a cellphone got past the door and caused every student in that particular classroom to go off the derech.
I wholehartedly agree 1) that cellphones do not belong in school, 2) that a principal should enforce that policy, and 3) that cellphones are spiritually dangerous.
But to say that it is literally (not figuratively, but literally) like a bomb at an airport is the sort of thing that turns off Yeshiva students to their Yiddishkeit. They feel like they are being played for fools and that pushes them away.
