Just because Europeans had a more superior culture (yes more superior, a slave-based cannibalistic culture is inferior) doesn't mean they were the bad guys.

Europeans ate people too and are in-fact the ultimate bad guy in world history

And the losers of wars will tell the tale the way *they* want it to be told. So what? What matters is the truth, and that isn’t decided by your status as a victim. Douglas’ point is that if losers have decided they want to selectively excoriate other cultures based on centering the bad and ignoring the good, winners can (and I think should) do the same with them. If you want to make an argument for your position, then make it. But if all you have is “f*ck what colonists have to say,” then the proportionate and reciprocal response would seem to be “no, f*ck what you have to say.” And since we’re talking about losers responding to winners, that seems an ill-suited response to secure any outcome the Maori may want.
