Making a programme that appears to condone a positive stereotype actually enforces all the negative ones as well. It says that they all have a valid point. To assert that Americans are naive, Germans humourless and the French arrogant is one thing: they're big enough to take it. But to say that there's a conspiracy of Jewish bankers, that gypsies are thieves, Pakistanis are dirty and refugees are muggers is something quite else.
The truth and the facts aren't necessarily the same thing. Telling the truth is the object of all art; facts are what the unimaginative have instead of ideas.
