Ah, but there is no escape from morality. The relationship between law and morality is intimate. The current battle with abortion is identical in many respects to the battle with slavery, except that abortion is not localized in the south. Would there be a war if it was?
The parallels are amazing right up to dred Scott and roe v wade. An industry thrives on it.
You have either to go to war or say that the civil war should not have happened.
I will sure agree that the Civil War should not have happened. The southern slave power should not have rebelled, and should not have started the war.
Their insurrection was illegitimate, and unabashedly in support of evil goals using evil means.
