Sam2- and DaasYochid: Hopefully, you don’t misunderstand me. I was around when R’Moshe zz’l indeed was the Possek of klal ysroel in America, witnessing his piskei din and the fierce opposition he created at times (just research the matter of artifical insemination) and you are right that the general population accepted his piskei halocho. Yet, there were other Poskim who had their own views, “bein lekuloh” bein lechumroh”. In the same way one cannot ignore-CH”V- R’Moshe’s influence on psak this past half century, in the same way, one should not dismiss the other Poskim, if need be. Do remember that this forum is for discussion only, not for psak. When one comes to psak, I would always consult R”moshe zz’l .
BTW_ I do not know what Rav Belsky shelita thinks about the eiruv. Enlighten me.
