Dear Youdont,
What is the point of responding to every little nuance in the teshuvos, if we can’t agree on what was Rav Moshe’s core opinion on eruvin? Who cares what type of psak he issued? First we learn ghow he understood rsh”r etc. Then we see how he worked with it through the sugyos. After we can discuss how he dealt with the halachic sources. And then finally we can come to how he encated hos shittah l’masah. Otherwise, it’s just you against whoever wants to give you an audience and it has nothing, absolutely nothing, to do with Rav Moshe’s opinion.
You have been on this for years and you never once bothered to respond to all the people who know Rav Moshe’s opinion. You only wish to force your thinking onto them by hijacking the Iggros Moshe. Well, I am cut out for that and it seems like I have gotten to you. No hard feelings, but where you the guy who went to a wedding and harassed everybody about the eruv, but then conveniently left when Rav Dovid zt”l unexpectedly showed up?
