I realized this yesterday: Representation is worthless in terms of peoples feelings, but it gives certain cultures examples of appropriate behaviour and people to look up to, so that they're not only influenced by their single parents and local culture.
This can be done in a natural way though. Take the movie Million Dollar Baby. The movie portrays a woman with strong physical characteristics but does so within the context of a good story that tackles a complex social issue. At no point in the movie does the main character’s physical abilities seem un-natural or forced. There are many other examples where socially desirable characteristics are portrayed by minority groups within the context of a good story without being forced or out of place.
