TF:RotF is not the most racist movie ever made, nor is it the most sexist, nor the most violent. It does have identifiable elements of all of these things, and it behooves us all to at least be aware of them, as their effect on people's perception of others (in this case, minorities and women) is insidious and difficult to combat, particularly when the people propogating such stereotyping might be themselves unaware they are doing it. Particularly if they are doing it in an easily-dismissable way through robots, or a cartoon bunny rabbit.
