NJ is definitely declining, but I wouldn’t say it is “turning anti-Semitic”; while this attack targeted Jewish people, it is hardly representative of the state. We have plenty of Jewish residents and elected officials.
Granted we don’t have daily killings of Jewish people in this state
But we do have a very vocal “Adolf Club” that rails against Jews daily here, stirring up hate and prejudices. Even entire town governments are doing this. Antisemitism is a problem here, and it is under reported because NJ is a leftist blue state so it can’t exist in the eyes of the media.
