I find it interesting to wonder what position we would be if the worldview was primarily Native American rather than Judeo-Christian. I doubt that we would be dehaling with such language extinction or the damage we have done to our world as a whole.
Overall, I have to say this is an excellent point. However, I think it misses the trees for the forest that has grown up today around the Native American myth. Today we see all these tribes as merely cogs in the Native American machine, but “back in the day” these tribes didn’t see each other in such a positive, embracing, dance-around-the-fire-together-for-solidarity perspective. They slaughtered each other, enslaved each other, wiped out ecosystems before migrating moving on to new conquests, and promoted their own cultural imperialism over other peoples. The New Age sweat lodge peace pipe mythology that we have built up today over the Native Americans and our national guilt to pay into the reparations of a “dislocated people” is the basis for perpetuating this good, wholesome, earth-centered masquerade is not enough to convince me that the Native American worldview would be any better (or any worse, for that matter) than the Judeo-Christian worldview that dominates our country today.
