Answer

Hello,
You’ve stirred up some nostalgia in me. So here is the plain truth.
This story is exaggerated, as myths usually are. If I remember correctly, there were two or three such notes, and both were protests about certain events, expressing a position different from the one Rabbi Blumentzweig had expressed (and therefore his “followers,” myself among them, saw them as attacks). I don’t remember completely anymore. One was after Ehud Barak visited the yeshiva as part of his election campaign. I opposed receiving him there (he was running an arrogant and offensive campaign), and I organized a protest against him at the entrance, contrary to Rabbi Blumentzweig’s position, since he had forbidden the guys from doing it (I told him that I would organize it and do it anyway, and then he canceled the prohibition). Afterward, when it became clear that I had been entirely right—that is, that the guy had basically insulted us to our faces—and following a similar argument a few days earlier about some of the yeshiva guys traveling to the Haredi protest against the Supreme Court (which I encouraged them to go to despite the rabbi’s prohibition—I’m not talking about hesder boys in active-service arrangement, of course, but older students), I hung up an angry note about “The Tale of Tzimkhonistan,” in which I came down hard and mercilessly on all of us, including Rabbi Blumentzweig, for naivete and stupidity and inferiority feelings. There were one or two other cases as well (one about supporting Moti Avitzrur in the elections in Yeruham, and maybe one more).
Following the note about Barak and the protest, the yeshiva was in an uproar. I myself was at home, and so was Rabbi Blumentzweig, and neither of us knew anything about the whole drama. A delegation of students from the first class came to my house (they were learning with me then, in my fourth-year shiur) and explained to me that the feeling in the yeshiva was that we were on the verge of a split/breakup. After I finished dying of laughter (if they had divided the yeshiva students between those who would go with me and those who would go with Rabbi Blumentzweig, it would have split 0 versus everyone else. And of course there wasn’t the slightest danger that anything like that would happen, not from my side either), I passed by him and told him what had happened and that in the middle of the evening study session I was going to gather the guys in the dining room to talk to them.
I rebuked them and told them that only in a museum do you walk on tiptoe. Someone who lives in a home and feels part of it doesn’t walk around on tiptoe, but says loudly and honestly what he thinks. I expect them too to say what they think, even if it’s against me and even if it’s against Rabbi Blumentzweig. Those who are terrified of any disturbance in the yeshiva are the ones who will keep a rosy picture of the yeshiva hanging on their wall at home while living their lives with no connection to what was there. A piece of irrelevant nostalgia. As far as I’m concerned, a study hall is a place for clarifying opinions and positions and for arguments, even heated ones. In a family you quarrel and argue, and sometimes you also really lay into each other. Needless to say, by the next day there was no trace left of any of it except for myths, some of which I now see made it to you as well. 🙂
By the way, I’ve used that museum-and-tiptoe metaphor more than once since then. For example, in column 63 on my site: https://mikyab.net/posts/3195
So that’s it. Those are the pieces of history. Regards to the yeshiva and all its staff. You can be happy that you had the privilege of studying there. It’s a wonderful place with wonderful people.
All the best and much success,
