Your patronizing attitude is not going to make your case. The 13th, 14th, and 15th Amendments abolished slavery, mandated apportionment by population, and removed voting restrictions based on race. However, it was not until the 19th Amendment that gave women the right to vote that our Constitution actually treated all human beings as equals.
Your thesis that evolution has anything to do with historical racism is inaccurate. People have used Scripture to validate many false concepts and slavery is one of them. The OT allowed for slavery and in the NT Paul instructs slaves to obey their masters. Your comment about that OT required slaves to be freed after a mandated length of time referred only to Hebrews who had sold themselves into slavery. While slavery was legal in the United States, Southern Christians were the major slave owners and abusers of human beings.
You can see racism is the development of African American Churches in this country; racism based not on Christian principles but arrogance and pride. If you think race has been eliminated as an issue in Christian churches today then you have blinders on. I lived in Houston for 23 years and say it on a daily basis even in the church and evolution was not the cause.
BTW, the 1830 date was a typo.
