Angelino Yid:
First of all, from experience I don’t believe anything said over in the name of Rav Moshe zt”l. Furthermore, I spoke to Rav Gruman as well. It’s clearly lies. Additionally, if these rabbanim would know Rav Moshe’s shitos in eruvin they would realize that he would allow an eruv (even more so the current eruv, which which makes use of omed merubeh).
“You Don’t Say tend to be Mevazeh Rabbanim that don’t agree with them.”
This quote of yours, is a bizyain, “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.”
