I think Craig Brougher has really put his finger on it concerning
historical roll lyrics.  Some may find it interesting that in recent
video re-releases of several "Our Gang" comedies (you know; Spanky,
Alfalfa, Buckwheat, etc.), a warning of sorts is presented in the
beginning that deals with the 'politically incorrect' nature of the
situations in many of these films (racial stereotypes, casting of
minorities in only subservient roles, etc.)

But they go on to say that "we can't change history; we can learn from
it and watch with educated eyes."  I think this advice parallels
perfectly the subject of these roll lyrics.  I recommend watching one
of these to anyone who thinks such media are valueless.
