Being that it seems as though you are both earnest in your assertations that you don’t have any idea what I’m talking about, I’ll try to explain A BIT.
Again, I am loathe to discuss this in public because then every balabos & his brother-in-law will throw in their two cents regarding an issue upon which they (myself included) have no right to offer an opinion.
Basically, the underlying issue is tznius, which would then lead to all other kinds of problems, as follows.
They felt that if an eiruv was put up, all the women would then want to gather outside with their strollers & shmooze. Being that it’s shabbos & you’re out in the street amongst the goyim (not in a bungalow colony) everyone would have to be dressed in their finest outfits which would then turn into a competition, which would then cause a major nisayon for a woman not to wear make-up on shabbos which would then cause the men to take note of all the women hanging around outside of shul, which would then cause a whole social scene to develop, which would then find each family’s boys & girls to also start schmoozing which would lead to………………………………………………………… which would eventually bring about the spiritual destruction of the community.
Unfortunately they weren’t as clueless as some of us may think & they weren’t paranoid either.
I have presented it very b’kitzur & will not get involved in a give-&-take on the subject.
Gedolai Yisroel don’t need me to defend them from every clown reading YWN.
(I don’t mean to insinuate that ROB or GAW are clowns, I’m referring to all the posters in general who seem to enjoy gedolim-bashing).
BTW I believe that R’ Aharon Kotler Ztz”l would not allow an eiruv in Lakewood for the same reason.
B’kitzur They were & are so strongly against it because they feel that it’s spiritual Pikuach Nefesh.
P.S. And by the way, for all you who think you discovered America they all also know all the Poskim who speak about how important it is for a community to have an eiruv, you haven’t chapped them on a mishna berura.
