Imagine that in Frontier times you have a nice home and yard and have a family of four. Imagine that a Lakota Sioux tribe comes to your door, and that you have no weapons to defend yourself, because Lakota leaders had previously removed all your weapons. They inform you that they will take your two children to a Lakota boarding school, and they would remain there until their schooling was finished, and you could not see them until their schooling was done. They further informed you that you would no longer be allowed to wear what you want, but only Lakota approved clothes. They also inform you that from now on, your food would be rationed.
Now you know the full story, and not white man history.
