Unlike American high schools, we don't learn American History, but World History and we don't detail it. However, I know some rough pictures on European immigrants invasion to New World, how they seize it from Native Americans and robbed them their culture, language and religion. As books also made by humans, they have a tendency to affect it whether it is good or bad. Winners write history (not to forget when reading history books).
I won't condemn the Americans because they have destroyed one nation to build a new. I won't condemn the Americans that they have destroyed one culture to create a new one. I won't condemn the Americans that they imposed their religion just because they believed that worshiping Nature is a fault. Because it is a human nature.
And here I enlist some speeches by Great Native Americans Chieftains:
If you have one honest man in Washington, send him here and I will talk to him. Sitting Bull
It was the White men found the yellow metal in our country and came in great numbers, driving away our game, that we took up against them for the last time. Rain-in-the-face
Hay, hay, hay! Alas, alas!' Thus speaks the old man, when he knows that his former vigor and freedom is gone from him forever. So we exclaim today, alas! There is a time appointed to all things. Think for a moment how many multitudes of the animal tribes we ourselves have destroyed! Look upon the snow that appears today - tomorrow it is water! Listen to the dirge of dry leaves, that were green and vigorous but a few moon before! We are a part of this life and it seems that our time come. Spotted Tail
........ They had signed the treaty under pressure, believing in these promises on the faith of a great nation. Little Crow
The man didn't know who he was. He only knew that he was an Indian, and that was enough for him, so he lifted his rifle to his shoulder and fired..... Death of Little Crow
He was a real hero of a free and natural people, a type that is never to be seen again. Author's note of Gall
Yet hear me, friends! We have to deal with another people, small and feeble when our forefathers first met with them, but now great and overbearing. Strangely enough, they have a mind to till the soil, and the love of possessions is a disease in them. These people have made many rules that rich may break, but the poor may not! They have a religion in which the poor worship, but the rich will not. They even take tithes of the poor and weak to support the rich and those who rule. Sitting Bull
