I think that a brief discussion regarding the subject matter, the white washing of slavery in the movie, the desire to let a classic remain unchanged, and the need for the discussion in the absence of historical accuracy in the movie could work if it's brief, well done, and if you can't skip it.
The Looney Tunes disclaimer fell on deaf ears. All that my Godson wanted to know is if Elmer was going to shoot Daffy now, or wait until they got home.
