One of the supposed differences between 'primitive' peoples and modern westerners is that while the former see the world in terms of their own society and 'outsiders', the latter have (for the last half century at least) aspired to a universalised view of humanity.
The trouble with the gringos is that they have a primitive collective unconscious - a culturally overpronounced limbic system. Even when they use the language of universality they do so in a rather blinkered and self-serving fashion. Most of the time though, the US-and-them, frontier mentality pokes through, unnervingly.
Broadly the Western world knows that injustice is the fate of anyone or anything that finds itself outside the moral community. Whereas liberal-minded westerners have allowed in all kinds of human former deviants and are now even considering the case of the great apes, non liberal-minded westerners (many of whom are located on the other side of the pond) are retreating into their homestead and planning a whole host of new evictions and exclusions.
