"... the existence of slavery by itself did not cause the Civil War. Not even a disagreement over slavery was the only reason for the war. I don’t know any reputable historian who believes this." ~Brooks D. Simpson, CrossroadsAh, but what historiographers and historians, reputable and otherwise, believe, and what they write and say and publish and blog about aren't necessarily the same thing.
The whole approach of "memory" and "era" type Civil War bloggers is to focus on slavery and basically ignore everything else -- in fact, to zoom in on it so tightly, nothing else shows in the viewfinder of their virtual camera.
Call them on it, and they'll say, "Well, yeah, such-and-such was a factor, too. I don't know any reputable historians who believe otherwise." And then they immediately turn up the zoom factor on slavery again.
I guess they think we don't know they're doing this, especially when they issue lame disclaimers like Brooks D. Simpson's example above....
