Here is a link to an article about one of the darkest chapters in recent Christian behavior: The title is "It’s Time To Be Honest About Native American Boarding Schools In The U.S." The link is Residential Schools Destroyed Native Communities In The U.S.,
I live in New Mexico and this is a very dark chapter in American history. The treatment of native children and the use of force to eliminate their culture was a disgrace of huge proportions. I personally knew a native man who, when were were in my car, pointed out where he was sent to a "school" and described the abysmal behavior of the so-called "Christians" toward native children. (He ran away numerous times but was caught each time and forcibly returned to the "school").
Although this situation has changed, the memories are still alive in native communities.
