More specific to modern colonialism
4) On the whole, where colonialism has advanced and receded (rather than advanced and stayed) it left countries in a better state than it found them. Of course that is arguable, but it means you can consider what is a "good state" - stability, freedom from want, justice & fairness, education - whatever.
5) The barbarism before and after colonialism was (is) worse than the barbarism committed during colonialism. Again arguable, but refer to specifics - India, clearly, has not descended into barbarism since the British left, but would any say that British Rhodesia was a worse place to live in the fifty years before independence than it has been, as Zimbabwe, in the fifty years since?
