Tales of the Raj tend to be rather one-sided. The eulogies talk of civilising a medieval part of the world with a unifying language, roads, railways, modern education, administration,justice and more. But when the critics weigh this against human lives lost in India and the inhumanity of the World Wars, the treatment of soldiers in the Afghan Wars, etcetera, etcetera, there is much for the blood to boil and keep simmering.
