Hispanics, who can be of any race, and who indicate that they are White + Non-Hispanic Whites = 75% of the US. Now tell me why Disney is not making shows reflecting those racial dynamics.
Maybe you should take a road trip across America in a bus called Priscilla and view for yourself the demographics of America. Then you may question why Disney is not making stories where 3/4 of their actors are white.
Hilariously, a huge chunk of the illegal immigration to the US is making the US whiter and "diluting" the black percentage of Americans.
