Asturias, "......just because it was "usual" doesn't mean it was right - even at the time." Almost right, except the last four words, where you are clearly alluding to latter day thinking.
We cannot rewrite history using the moral and populist values of the present, colonising (aka subjugating) was a popular sovereign nation pastime historically, English, Dutch, French, Belgium, Italy, Spanish, Portuguese, German, etc.
We used to deport people for stealing a loaf of bread, it served a purpose then and when America decided it didn't like cups of tea anymore, we then deported them twice the distance to Australia because it still served the same purpose, which was right then.
Rewriting history against a modern context appeases no-one who was wronged at the time, we can't heal the pain of all the peoples taken into slavery, we can't vacate the new world(s) and give them back to their rightful owners, as always we have to look back and realise that we can do better.
