I've never seen any evidence of anti UK bias and I've read the Graun for years. Anti-USA? Anti-Trump certainly, but how can one believe in common human decency and not be anti-Trump? Israel, likewise. Most informed people are opposed to Israeli policy - after all I am, and I am a Jew. Whether Israel should even exist, or be obliterated - that's a much more dangerous argument and the Guardian, understandably, recognises both views.The Guardian is festooned with anti Uk bias surely you are aware of that? It is also anti USA (even prior to Trump) and Israel in outlook.
Perhaps if the poster were to read more of the Guardian's articles, he'd appreciate that they sometimes print views which are decidedly right-of-centre and pro-brexit. Not often, but they do.
