So everyone please stop trashing Robert E Lee and Stonewall Jackson.
no
Jackson was revered by many of the African Americans in town, both slaves and free blacks. In 1855, he was instrumental in the organization of Sunday School classes for blacks at the Presbyterian Church. His second wife, Mary Anna Jackson, taught with Jackson, as "he preferred that my labors should be given to the colored children, believing that it was more important and useful to put the strong hand of the Gospel under the ignorant African race, to lift them up." The pastor, Dr. William Spottswood White, described the relationship between Jackson and his Sunday afternoon students: "In their religious instruction he succeeded wonderfully. His discipline was systematic and firm, but very kind. ... His servants reverenced and loved him, as they would have done a brother or father. ... He was emphatically the black man's friend." He addressed his students by name and they, in turn, referred to him affectionately as "Marse Major".
You think describing the "ignorant African race" means that the slave owners who said that were... um... remotely objective?
I don't know why everyone's obsessed with treason and traitors, but yes, the Free States of America would be traitors, and the remaining USA would not have conquered them or put up statues to them. Of course, treason in the name of abolition and treason in the name of slavery and greatly expanding slavery are not both morally the same from any objective point of view.
