The problem is, even if the reenactors are clear that's the goal, which they rarely are, if the spectators are also not in on the gig, then it becomes misrepresentation. There are a lot of things you can depend on the average spectator to pick up, but in my experience, this isn't one of them. If this question about kilts keeps popping up here (where I assume most are at least slightly more than casually interested in the ACW), what kind of effect does having guys in kilts and poorly researched confederate marine uniforms have on the spectators?
