Let’s also congratulate the Brooklyn frum community for its accomplishments in terms of sinas chinam and mentchlichkeit.
When the Flatbush eruv was first erected, it wasn’t usable because the eruv would be torn down every week by the detractors who sincerely believed it was a mitzva to do so.
In addition, there was a civil war in effect in the community: families were split apart; friends became enemies; people who used the eruv were not allowed to eat in the same home as those who didn’t; shidduchim were broken; Rabbonim were abused; mothers with babies were harrassed. Boruch Hashem this is all past us.
