Power Line notes the amazing story of an indigenous tribe in the Amazon which has been untouched by outside influences. Survival International claims that 150 million "uncontacted" tribal people live in more than 60 countries around the world. "Isolated" is the politically-correct term, apparently - as many of these people have been contacted, but have sought to remain insular.
The status of these people is extremely interesting. One cannot avoid the paternalistic role demanded of states within whose borders these people live. Well-intended activists wish to create a legal mandate that nations recognize and enforce these people's isolation. But this seems, in itself, a somewhat egregious form of evolutionary control. It is a peculiar accident that these people have been excluded from the progress of the entire human species. Surely it is an authoritarian act to decide that they must remain in such a state until they sua sponte develop a social instinct to the contrary. One may suggest with equal validity that they should be contacted immediately with a reader's digest update on what they've missed over the last several millenia or so. Who knows, they might like football, pizza and the Beatles.
Whatever the answers, that these people must obviously be treated differently than others people in their respective countries is a notable commentary on the equal application of laws (they aren't paying taxes on their war paint and spears, after all, and I assume they are administering their own "cruel and unusual" forms of punishment). One cannot help but to draw back from this extreme example to more mundane social perplexities, such as religious and cultural minorities which might seek similar accomodations. Muslims might well ask: if them, why not us also?
