"Inappropriate unprofessional unsourced editorializing?"
The Economist explicitly brands and declares itself a journal of both reporting and opinion. As for "unsourced", it choses to adopt an anonymous style and tone of writing (such that any statements of opinion, which in any case are hardly disguised and pretty obvious to spot as such, take be taken to be the opinions of the entire editorial board, more or less).
As such, it's one of the few organs (though I frequently find myself in disagreement with it) I almost always enjoy reading.
