Discrimination is a universal theme. A common false assumption is that black people are the only race/culture that are being affected by racism/discrimination. However, this can apply to Asians, Hispanics, whites and every single other race as there is no "perfect" race. For example, some people say, white people cant make a certain type of music, white people cant dance, and the list goes on for all the other races.
Discrimination is a universal theme because if you are separating one race you are also separating the other, and in the same fashion, discrimination can apply to any other race/culture.
