No, You're the one stretching things. If you want to provide an example from The Guardian that actually works, and it is as easy to do so as you say, go ahead. As I said, I wouldn't be surprised if they had a blind spot, given who is on the staff and the byline of this very piece. But you haven't here.

Rather, you've showed an article where the primary complaint of the headlined report, that the potential biases of a commentator or a source are not made apparent, does not apply because the bias of the person quoted, that xe is politically connected to the government whose actions are being scrutinized in the piece, is very much given as context.
