The good news is that absolutely no one is inconvenienced or harmed in any way by the Jews’ creating an eruv for their community.
This practice is not an obvious “Oh, yes, that makes sense,” and even more explanation might lead to even more head scratching on the part of those who decide to be free from restrictions. The whole thing is pretty innocuous and should be ok, if only from a multiculti point of view.
One can argue that if the U.S. is not complaining about Muslim mutilation and honor killing of its girls in the U.S. or Muslims’ quoting their religion in cutting off the hands and heads of other humans, then overlooking a stretch of wire put on top of some posts by Jews ought not seem such a terrible “offence.”
No but it does point out the willingness of the community to justify anything.
