Do you read the Guardian? I do, practically everyday, and I can say - As someone is centre-right, i.e. not the guardian's idea of their readers - that just isn't true.
This comment ignores the existence of Owen Jones, of course, but still.
I agree this news is pretty sad. The Guardian has no objectivity any more. I wish it were possible for newspapers to survive as non-partisan entities, but it's looking less and less likely that'll ever be true.
