Japan went from a Dark Ages sword swing head choppers into the modern age in TWO Generations beginning in 1853. Yet many of the Indian tribes still long for the Stone age after 400 years of intereaction with Europeans.
That is because Japan has/does not have a communist faction in their society spewing revised and unrealistic historical events-I guess they get shouted/smacked down pretty quick over there. In the US and Canada there have been socialists/communists preaching/indoctrinating Native and other kids for more than a century. Place the blame where it belongs-on a society that permits these Marxists to continue preaching and indoctrinating. Stop that and you get rid of the fake history-it starts with getting rid of the current public school system-blow it up and do something that makes sense...
Also relevant, I think is the fact that Asians have totally different morals, customs, sense of humor and even think differently than Caucasians or Blacks-and have for 1000’s of years. Their societies are much more regimented and contained.
