Neville,
“Ah, ok. So, it’s just that you guys feel qualified to “correct” the posek hador. ”
Please re-read my post: I am not correcting the posek hador, rather the information he was fed by people who had sinas eruvin. To the contrary, according to the facts Rav Moshe presents in his teshuvah, he is of course one hundred percent right. The problem is that those facts don’t represent reality.
I’m actually wondering whether you ever read the teshuvos inside?
Apparently not. It’s for free on HebrewBooks, so why do I have to write them out to you. Go ahead and learn them.
