Life is more complicated than that, Iains. You also have the selection of which facts you choose to report and the way in which you report them. An entirely factual report can - and frequently is - spun to tell a story to match an opinion. Guido does this all the time, as do many others. If A and B both occur, reporting just A, just B, A as if it causes B and A as if it is caused by B are four distinctly different 'factual'stories.
