I agree, to some point - Anglo-Saxons/"white" people that came to the New World, were, for the most part, portrayed in a negative manner; at least in every course I've taken where the issue comes up (a healthy number).
But isnt it true?
The article makes me think that what Pearson is describing happened in Australian school systems only, perhaps. I know for a fact that in this particular part of Canada, the rituals and traditions of Aztecs, Mayans, etc. that seem 'barbaric'
arent portrayed in a mellowed light; the teachers just try to make sure that we understand the
why behind the rituals - we dont want kids growing up thinking that they performed human sacrifices just for the heck of it or because they were bloodthirsty maniacs.
In my Ancient Civs, and Early European History classes, we explored the accomplishments of "Anglo-Saxons" and their ancestors/relatives thoroughly, but teachers didnt shy away from the more brutal practices like the Welsh scalping their enemies alive and leaving them spread-eagled, or William the Conqueror's men burning the eyes of Welsh rebels with hot iron rods.
In the Western world I think it's very easy to jump to wrongful conclusions towards cultures about which we know very little; that's why the extra effort needs to be made to understand them better. America's always at war - with Bosnia, Iraq, Afghanistan, Vietnam... it's easy for "patriotic" people to hate those cultures without any valid reason; and encouraging the celebration of diversity can only be a good thing in my view.
