Now we know where they learn it.

As the article says you have to admire the sheer bloody-minded consistent bias of the Guardian’s editors. Not content with constantly posting articles about Israel devoid of context, they admire how a photographer has created an image “divested of context” designed to show a solitary figure we are obviously supposed to assume is a “Palestinian youth” being bombarded for no particular reason in a huge “assault” of tear gas fired by, we are supposed to assume, a myriad of Israelis.
Much the same as the anti-Israel bloggers here - who fall over themselves in finding out of context stories with which to pillory Israel but I have yet to see them post anything showing the Palestinians, who they profess to support, in a good light - I wonder why? (Or maybe I don't!)
