The people opposing rights for Blacks were almost all, 100% White Christians. Not only did the White Christian Churches (including some from the denominations listed as supporting rights for Blacks) oppose equal rights, They preached against it from the pulpit and they actively tried to avoid the results should Blacks actually succeed in gaining rights like riding on the same bus to school as the white kids or go to the same school or live in the same neighborhood or eat in the same resturant.
How many of these churches were Southern churches rather than northern or western? That is, I think this was predominantly a Southern phenomenon, not a Christian phenomenon, but perhaps you can correct me.
