... and the British (and everyone in the 'enlightened West') are taught that savage destruction of Asia (incl. India/China) by European powers was for their own benefit and that they ought to be grateful for having had their ancestors murdered, subject to famine, and sometimes outright genocide (not to mention having their cultures completely destroyed to the point of total alienation).

They even do this with the so-called 'enlightened Islamic invaders' in India. The West has pathological hatred for the 'inferior pagans' and it shows very clearly; and indeed there's very clear evidence for this in white-supremacist fields like Indology[1], where half their time is spent bad-mouthing India, and the other half appropriating her.
