He wasn't being racist, just employing obsolete anthropological terminology.
But then how does this square with his remarks being "true", as Ms. Wente claims them to be? Anthropological classifications, presumably in this case something like Lewis H. Morgan's phases of cultural evolution, come and go for the same reason as they do in other areas of knowledge: they are superseded by better and more accurate classifications. The obsolete classifications are then generally referred to as "false".
In any case, its wonderful how Ms. Wente turns a bit of idiocy on the part of Dick Pound into a bout of native bashing.
