The world evolves right over the lands of the cavemen....
There are plenty of recent films, shows, and entertainments out there that have few to no minorities in them, just as there are many shows where no Caucasians make appearances.
What the newer models provided through entertainment show, is that skin color and gender make very little difference to the actual tale or stories told.
I'd advise you to evolve as the world evolves if that were an option.
