n0mesorah,
“The Yeshivshe Velt takes the Brooklyn Eiruv personally because it was aggressive toward the status quo of the leadership at that time. It was much more contentious then eiruvin that had a lot less validity.”
Not the reason at all. The only reason was because they did not respect the opposition, and maintained that one cannot argue on Rav Moshe. Nevertheless, most the those in opposition did not know the inyan. The aggressiveness was from the anti-eruv group.
“It’s one thing to claim that a Ry doesn’t know the halacha. It a whole nother ballgame to claim that a RY is being paid off to be against the Eiruv because he doesn’t care about the Torah. Do you really want to go through all the mud?”
There is nothing to go through. Its fiction. No one claimed that the RY were paid off. The only argument was that they were not baalei halachah.
