But those texts you praise were also written by "revisionists" who strove to make slavery look like less of a problem than it was taken to be by the Civil War generation. It shouldn't be assumed that early 20th century Southern historians gave a true, "unrevised" view of slavery or that distortion or bias only came later.
Maybe the revisions have been revised again and again. But this is a particularly thorny issue for me, since my family -- and others -- came to the New world in 1621 as indentured servants, before the slaves arrived and did the worst of the heavy lifting. A fact that has been totally revised out of history.
