As a people the nations were highly susceptible to introduced diseases beginning with the first landing of the Euro boat people. the same susceptibility can be seen in modern day uncontacted tribes.
This isn’t a matter of happenstance or weakness, what it has to do with is the reality of the nations having being a genetically pure and distinct people.
Immunities developed as the result of comingling with Neanderthals, who as a robust people genetically generated immunities and passed them on to modern day homo sapiens, to what became the Euro boat people.
A distinct people, no matter how any would slice and dice that it is, or was, the reality of the nations – no Neanderthals in the woodpile.
As our ceremonies, traditions, and indeed way of life are being corrupted and perhaps irreversibly altered it is food for thought as we like all people, all cultures, are more than our physical bodies.
Every ceremony or tradition that is commercialized, every new age or foreign concept inserted into them carries with it a susceptibility of it’s own, an infection that attacks the cultural and physical body of who we are.
Individuals among our own like Dennis Banks, Leonard Crow Dog, Clyde Bellecourt, and the late Russell Means among a growing number of others who engage in this commercialization are in effect the current invasion of boat people, new Typhoid Marys.
Money doesn’t trump the need or importance of being who we are, neither do fb pages, faux titles, or the attention seeking devices of attire and pipes.
This being the internet I am sure there will be those who read what they want into what I have said – so I further add that I don’t believe there has ever been or ever will be a super race, as the one thing all humanity shares are flaws – none perfect.
When it comes to the Bering land bridge migration I wouldn’t argue either side, but if Asians shared the same immunities as Europeans and the nations didn’t a question arises to my way of thinking related to the land bridge migration theory.
Some of the comments in first link seem to validate the Neanderthal influence.
