Most other places that I "hang out" online, I am considered an "expert" on the Confederacy, if not "the expert". I pretty much run into no one that has a clue about Confederate military law...and when they do it is normally "what they heard" or "what they assumed".
[Here at this board I usually feel quite inadequate and humbled by the huge amount of knowledge that exists here now, and the knowledge of the men who have since moved on or passed on (Art Bergeron, Fred Cox, and a couple other awesome guys)].
I would go so far to say that less than 1/4th of the "fans" of the Confederacy actually know anything at all about Confederate military law, and that is a quite conservative guess.
