Nobody has yet cited anything offensive from the article (which is not linked). It is not at all offensive to report on the (official) poverty level, and the same report about black people would not elicit even one word of protest. Everyone takes it for granted that poverty is common among black people, and nobody objects to anyone pointing this out.
Nor is “insular” at all offensive. On the contrary, to us it’s a point of honor. We are <i>proudly</i> insular, הן עם לבדד ישכון , and it’s one of our greatest and most cherished traits. Why should we be offended when others acknowledge it? I think those who object are secretly sorry for it and wish they were more assimilated with the nations.
