Not a Christian Nation

Neither the colonies nor the United States was ever a Christian nation and we are not today. If we were was, it owning human beings like property that exhibited our Christianity? Do black people still rate at 3/5ths of us white guys? Or was it our habit of murdering all the natives, men, women, and children we found and stealing their property? Killing those children may have set God against us. Didn't Jesus say something about having a millstone around our neck would be better than doing what we did? I believe his name was Standing Bear. He went all the way to the Supreme Court to have himself declared a human being. That was in 1903. To the Supreme Court means the system fought him all the way. So for the first 127 years of our existence our Christianity was exhibited by our acceptance that the Native Americans were not human beings.
