“Rav Moshe did pasken against the LA Eruv. It is a controversial Eruv.”
He did not, show me one teshuvah where he mentioned LA. It’s all heresy.
“There are rabbanim that say that Rav Moshe wasn’t given the correct metzios. There are other rabbanim who were there when rav Moshe was asked who assur the Eruv.”
So what, some say that Rav Moshe wasn’t given the correct metzios regarding Queens. But since Rav Moshe wrote a teshuvah allowing the eruv that is what counts. I don’t believe any of these stories, they are all made up after the fact.
“I even heard one of those rabbanim say that they would not use anyone who carries in that Eruv to be an Aid at a Chasunah.”
Shame on him. Rav Moshe wrote (1:186) that when one follows one’s rav on any issue, even on issurei chilul Shabbos, albeit the halachah is not like their rav’s interpretation, no aveirah is transgressed.
