The cold hard reality that the natives of this country refuse to accept is that their ancestors were conquered peacefully but conquered nonetheless. While the Spanish conquered and colonized other cultures with a common theme of extinction , the British were more measured and humane. There is no talk of theft or stolen lands in the U.S. The natives there know that their ancestors warred and were handed their hat. 
Every inch of Europe was conquered at reconquered over the past 2000 years. Britain was conquered by the Romans who stayed for 400 years and later by the Normans of France. Scotland was given the gift of red hair by the Danish Vikings. 
I find it particularly galling that the natives of this country feel that they are so special that despite being a stone age neolithic culture that failed to advance one day in 1000 years, they are entitled to special treatment no one else in world history has had and  they never gave their own neighbours .
