Let me ask---why do Europeans call us "Red Indians?" We're not red LOL.
Heh, and not indian either.
And asian people aren't yellow, black people aren't black, white people aren't white. These colour codes are just remnants of old racial theories and classifications. Unfortunately still quite potent (give colour pencils to a kid, and he'll use them to split humanity into the number of distinct "kind of people" he's been taught to compartmentalize - whether or not he's been taught to see these groups as "equals") and still used by some administrations ("race" entries in some files). The day we'll manage to see objective skin colours without being influenced by these predefined colour categories, racial theories will have made a huge step towards oblivion. But, well, science permeates "common sense" and "popular wisdom" extremely slowly...
As for Tintin, at least those stereotypes were used to denounce inner colonialism, long before the trend of pro-indian westerns, etc. The intention makes them less shocking. Still, the whole caricature would probably look a bit redundant, now that people have more distance and critical information about the history of the USA. Also, the satire on redneck racism would be a bit extreme, although it still makes me laugh in the albums (the french version of "I raised the alarm and we hanged a few fellers right away but the thief got clear" is "I raised the alarm and we immediately hanged seven niggers, but the culprit escaped", and the "forty-four hoboes" lynched as the radio announces it later are "niggers" in the french version too). According to Herge, the KKK was very powerful at that time, and that's also something he wanted to criticize. I find it strange that the translation censored that.
Anyway, I'm not certain this album has aged very well. A movie would have to take place in the past, but maybe also to be adressed to readers of that time. It would be a bit too didactic for today, and its sarcasms would come a tad too late.
