Will this be accompanied by other countries rewriting their histories to reflect the contributions of the British?
Yes, but only using terms like "oppressor", "hegemonist", "imperialist", "colonializer", "tyrant", "overlords" and the like.
The equation works like this: West = bad. All else = good. Or, more simply, everything you know or have ever been taught = wrong. Revisionist lies, claptrap, and propaganda = right.
Comprende?
In Mark Steyn’s book “America Alone” he says if you ever doubt Great Britain’s contribution to the world ask yourself one question. “Would you rather do business in a country that was once a British Colony or one that wasn’t?” The answer of course is a no brainer.
