Here are some examples of articles and videos that demonstrate the weaknesses of multiculturalism and racial diversity in the United States:
In Oklahoma, a white kid was attacked on a school bus by a bunch of blacks for just being white:
Here is another news video that highlights the racial conflict between blacks and hispanics:
This is another video that is an example of the mentioned conflict above, but in this one black girl was murdered by hispanics, just for being black in the wrong neighborhood:
Here is a news video about a white boy beaten up by blacks on a school bus. Notice how the white boy was called all these anti-white slurs.
Here is an example how having a diverse nation could jeopardize national security risk:
This story focuses on how a Chinese man exported U.S. military “know-how” to China. His allegiance was not to the United States, but rather China, and multicultural nations make it easier for a native from another country to export military secrets back to their own country, because multicultural societies do not stereotype and view everyone as a same, and believe that immigrants and other types of foreigners would not be capable of such a thing.
In a more recent story, an 11 year old hispanic girl was raped by 18 black boys. You can find the story here:
To sum up, multiculturalism and racial diversity leads to unnecessary conflict because different groups have different interests and needs. This can be illustrated by the numerous race-based organizations that advocate for their group’s interest, such as the blacks have the NAACP and Black Panthers while hispanics have La Raza and Mecha, and of course the Jews have Chabad Lubavitch, ADL, SPLC. In addition, the whites have the Ku Klux Klan and the Aryan Nation, which is rather small and not nearly as effective as the other racial groups advocacy. These group interests as illustrated here only leads to suspicion of other groups, which eventually leads to unnecessary violence and racial tension, in which each group tries to oppress one another.
