לכבוד הגאון וכל חברייא קדישא
Every subject is open for discussion, and good respectful discussion is very constructive, nonetheless all discuusions should take place within parameters of דרך ארץ and מענטשליכקייט. this is especially true when discussing the opinions f גדולי ומאורי הדור שליט”א.
הזהרו בגחלתן.
I have already written that the מחבר clearly says ששים רבוא עוברים בו בכל יום if one understands this כפשוטו then you are obviously right there is only one שאךה is there 600k daily or not. As the ט”ז and מג”א both agree that אין למחות ביד המקילין then obviously virtually every eiruv is kosher.
Nonetheless, there is a suggestion – primarily by הגאון ר’ משה פיינשטיין about brooklyn and the מנחת יצחק about London, to say that the מחבר does not refer too a literal 600k every day, rather, basically, the מחבר means a street which is מיועד for 600 k. Exactly what each pisek held, and exactly how one is קןבע the מציאות can be debated, and it remains הררים התלוים בשערה.
The עדה החרדית ערוב בירושלים עיה”ק excludes כביש המנהרות – 9 it also excludes כניסה לעיר and a couple of other roads.
as far as I understand, this effectively means that הגאונים ר’ יצחק טוביה וויס ור’ משה שטרנבוך שיח’ are excepting the שיטה of the מנחת יצחק and therefore make a point to exclude these roads. [ As a matter of interest Rabbi Weiis , Rabbi meir bransdorfer זצ”ל, abd Rabbi Roberts all consider themselves תלמידים of הגאון ר’ חנוך העניך פאדווא who also expressed opposition – at least verbally -for the London eiruv. ] על כל פנים this is the basic of the eida hachareidis who are clearly differentiating between London and yerushalayim.
The same applies in בני ברק the גאונים ר’ שמואל וואזנער זצ”ל and יבלח”ט ר’ ניסים קרליץ לרפו”ש have excluded כביש 4 from the eiruv, again R’ Chayim wosner has said that one may not carry in GG.
There is another big heter for roads, and that is by making אינו מפולש. the דברי מלכיאל clearly writes that a road that bends is not a רה”ר , police barriers לכאורה are at least equal.
BTW, in case you guys are convinced that I am a card carrying anti eiruv member, I left golders green twenty years ago. When I was there no one walked around wearing a tallis, yidden joined in the VE day celebrations, Rabbi Jakovitz was chief rabbi, and corporal punishment – including shoe confiscation – was still used in all schools.
