"It is all a load of nonsense, I suspect the paperwork was destroyed as they realized right-on liberal lefties like the Guardian and its readers would go over the op on it."
Oh, well. That's all right then. I guess we can destroy as much evidence as we like for fear of letting those damn liberals seeing it. Never mind atrocities being committed by British soldiers, nothing matters more than keeping information from the liberals. I'm astounded by this comment.
"How many ordinary people were involved in the days of imperialism, it was mostly our own lords and masters, who held sway not just over dominions and peoples overseas but those on British soil."
It depends what you mean by 'involved', but I think you can make a case for pretty widespread involvement. There's been plenty of research indicating how extensively felt the economic benefits of Empire were - from commodities and materials being imported, to prized trade routes the Empire had generated - that certainly in the later parts of the C19 and during the C20 were extensively enjoyed by the British public.
In addition, there's also the fact that you can't really understand the modern world without understanding colonialism - the history of India and China, for instance, were both extensively changed by the actions of British imperialists. If we want to understand the modern world, we should care about attempts to rewrite history and be wary about the motives behind them.
