"Or alternately, if ethnicity isn't what you're using as your basis for calling groups of people and their children "uncivilized", what is?"

Culture.

I simply spoke of generic nomadic uncivilised hunters.

And not at all in a bad way, just to illustrate a point. Because to my knowledge yes, nomadic hunting cultures do have similarities. Education seems to be one of those.

Feel free to provide counter examples.
