This demonstrates yet again what happens when a brain is infected with the religion virus. Doug Wilson, a megachurch pastor from Boise, Idaho, argues in his newly released book "Black and Tan" that the abolitionist movement was wrong and the Civil War should never happened, because if Southern slave-owners had been allowed to implement the Bible's teachings on slavery, then a more humane transition would have taken place through "gospel gradualism."
"If we could bring an end to abortion in the United States by precipitating a war (or by trying to), should we do that? Abortion is at least as great an evil as slavery was. Abortion is at least as great an evil for black culture as slavery was. If you allow for gospel gradualism now, then why is my urging a gospel gradualism in 1858 a thought crime? And if gospel gradualism was sinful then, why isn't it sinful now?" 
2. "Liberal" Christians have used the Bible's endorsement of slavery as a means to dislodge their obedience to the Bible's teachings on female submission to their husbands and homosexuality, so if Christians are going to hold onto the "biblical" view of marriage, then we have to be pro-slavery as long as it occurs in biblical terms.
"Christians must live or die by the Scriptures, as they stand. Compromise on what the Bible teaches about slavery is directly related to the current pressures to compromise on abortion and sodomy. Southern slavery was an example of the kind of sinful human situation that called for diligent obedience to St. Paul's directives, on the part of both masters and slaves. Because this did not happen, and because of the way slavery ended, the federal government acquired the power to impose things on the states that it did not have before. Therefore, for all these reasons, radicalism is to be rejected by Christians." 
3. If Southern whites had been allowed to gradually grow out of slavery on their own through the Christian teaching of their pastors rather than having emancipation forced on them by the federal government, then we would have a better balance of power between state and federal governments today.
"The discipleship of the nations is a process. This means that the South was (along with all other nations) in transition from a state of pagan autonomy to one of full submission to the Lordship of Christ. Christian influence in the South was considerable and extensive, but the laws of the South still fell short of the biblical pattern. In spite of this, the Christian influence on antebellum Southern culture surpassed most other nations in the world of that time."
