Dear Youdont,
I do not agree with anti eruv group. They are going to reimagine everything just to get their point across. But they never learned enough to make their own points. So they will just go around in circles, destroying whatever they are entrusted with.
But there is something else going on here. And you blissfully ignorant of it. Or doing a great job of faking it. You are throwing every half source at the issue to try to force it. Never mind that the petitioner didn’t care for any sources. He would carry as long as we (Or his real world associates.) don’t attack him for it. He is not here for the Torah at all. Neither are you.
Rav Shmuel Birnbaum, Rav Yisroel Belsky, and Rav Aahron Shecter, could have went to speak with Rav Elyasiv in person and he wouldn’t have felt the need to go along with them. No American Rabbonim where able to pressure him. There was a lot of people keeping him away from the public. Maybe you are lying on purpose. I can’t tell anymore.
Rav Elyashiv paskened against the eruv because of the only person who he esteemed for his Torah Knowledge. That is Rav Dovid Feinstein. Rav Dovid almost never got involved in halacha battles. Here he even brought in Rav Elyashic and Rav Chaim. He was very confident that he was right. And you shrug. Until you claim that he was mislead or whatever.
