But take some examples to the contrary, Greg. It's a fact that many Southerners who had voted in the 1866 election were prevented from voting in later years by the Test Oath. It's interpretation that says this was due to their refusal to take the Oath (and an erroroneous one given the actual oath itself) and an as to whether or not that partcilar version of the Oath was justified by the circumstances.

Vigilante organizations (even that word is an interpretation) commited acts of violences against Northern sympathizers and blacks. Why the did so is open to interpretation. They say that they were supressing lawlessness that the Army wouldn't or couldn't control. You say they were racist murderers. Problem is both are probably true. On the other hand the assertion that these groups were part of the KKK is an opinion and one not supported by any factual evidence, as the groups were distinct and cannot be shown to interacted much less merged.

See what I mean? Not being pedantic, just pointing out that a lot of things people call "facts" aren't.
