The original original thread was the troll, provocatively substituting "who loathes the USA" for the BBC's more carefully chosen "Quiz: How widespread is anti-Americanism?"
The BBC may sometimes follow a government agenda, and it would hardly be surprising if this were particularly in evidence in their world service, but to describe it as yellow journalism is ludicrous. Unless they produce a specially dumbed-down edition to match some of the crud that Middle America is exposed to.
