Districts are specifically formulated in major cities to have enough black folks (a large majority of the residents of the district, usually) to elect black congresspersons, Hispanic people to elect Hispanic representatives, and I'll bet in California at least, the effort is made to elect Asians to Congress. What is the point of all this?
In theory, to mitigate past discrimination. Beyond that, I believe it is because different races wish to have their own people represent them. It is a matter of trusting people of their own culture and skin color to represent their interests.
So, how does a multicultural democracy overcome this inclination to achieve national unity? Obviously, since the US is temporarily a majority of white people, we have overcome this inclination and embraced cross cultural leadership. Or have we done so? Has America ever been so divided?
In the meantime, in Asian countries, they elect Asians. In black countries, they elect blacks. In Latin America, with the one exception I know of where a Japanese man was elected (and later convicted of bribery, Fujimoro?) they elect Latinos. In Muslim countries, they elect Muslims. In India, they elect Indians.
The world is full of a bunch of mother fucking racists!!!!
