Ghost dog...you are correct, that is a fact, but with all due respect to our aboriginal folks...
many in this world, in our life times, have gone thru that same set of circumstances. I am betting nearly half of the people that came to the US, Europeans, Asians, and nearly everyone else, has fled their country, their lives, their customs, their language. They came here, some because they wanted to, but many more because they had very little choice, due to war, due to work, due to social disparities of all sorts.
My early family came here to escape the ravishes of World War I. All the above changes were faced by each of them.
This goes on yet today, even as we sit here and chat.
I don't like it, but I also don't have an answer.
People have been this way since the beginning and to my knowledge no group so far has been absent this trait.
Someone different is not so easily taken in, is not so easily accepted as equal, and in fact is very easily, maybe traditionally, called upon to be the scape goat of our own problems. Couldn't be MY fault, must be HIS.
Maybe that is one thing we can all work on.
