What is your position on race in media?

If you are into any kind of form or fiction -be it movies, comic books, video games, etc.- you have heard talks about diversity, representation, race swapping and more such topics – all having to do with race in some way.

I would like to know if there is a way you boil down your opinion on these array of issues. What would be the liberal position or positions? When should the race of a character matter if ever at all?
