You seem like a decent person.I suspect you have told some lies as families of color didn't socialize with their white employers in the south during the 50"s and 60' or 70's. Having spent time in Alabama in the early 70's it was obvious that the races did not mix and the tensions were high. 
 Yes some whites marched for civil rights but not many southerners, It was a mostly black movement.
  So called Christians are also the people that kept slavery going and wanted to destroy the civil rights movement.
 Unfortunately the evils of 2 centuries ago still are stuck in some peoples attitudes today and even in the very near past that some seem to want to go back to today. 
Since you feel all these evils that happened in the south were all settled in the civil war and after that blacks and whites were one happy family, can you explain to me all the lynchins of blacks in the 50's and 60's when we were all being so enlightened?  I think you just can't understand your own racism. Peace,when?
