It’s very easy to fit something to a pattern retrospectively. It’s also, very often, inaccurate. In this instance, how exactly did the Guardian “have no other choice”? If they’d been somehow forced to cover this story against their will (and I really can’t see how they would be), they’d have given it as little prominence as possible. As it was, they gave it several articles - and prominent ones at that. It was from the Guardian that I first knew about this particualr episode.
Not only that, but they also published an article analysing the issue, written by Patrick Wintour, one of their senior journalists. Presumably they also “had no other choice” than to do this?
There’s a difference - and a very large one at that - between reporting an allegation and saying that it is a fact. If someone prominent is accused of anti-semitism, for example, this is likely to be reported. Such a report is not necessarily agreeing that the person in question is anti-semitic, it is merely reporting the accusation. Your view seems to be that reporting such an accusation is tantamount to agreeing with it.
Lewis mentions the Guardian’s treatment of Malia Bouattia as an example of its alleged pro-Israeli, McCarthyite stance. He accuses the paper of smearing her. Try searching on her name on the Guardian web site and these are the first lot of results, in order of their appearance in the list:
Such smears. Such McCarthyism. And yet you’ve desribed Lewis’ article as “extraordinarily well researched”. Well yes, as long as your idea of research doesn’t stretch as far as the writer actually reading the paper that he’s making accusations against. It seems to me that, in this instance at least, Lewis seeks to establish a pattern that suits his way of thinking, then fits things into said pattern where possible. Anything that doesn’t fit the pattern is simply ignored.
Over the years, the Guardian’s reporting of Israel has, for the most part, been anything but pro-Israeli, or at least that’s how 've read it. They have voiced strong opposition to any number of Israeli policies, and continue to do so.
