This is fascinating. Now you think Rav Moshe was tricked by “askanim” and didn’t find out the basic facts before making a psak which he knew would severely inconvenience the largest frum population in the world.
And that nobody bothered to correct him, or he just blindly ignored them.
Yes, if that is who you think Rav Moshe was, then you should not listen to him.
However, that is not my Rav Moshe. And you should not think that.
But, out of curiosity, tell us about these “askanim”. Just what was motivating them to want there to be no eruv in Brooklyn?
Did they own real estate in queens?
You are going really far out here in your need to carry your tallis to shul. Why don’t you just bring it on friday and you can go back to respecting gedolim.
