America being 'colored-less' has created many problems in our society. There is an attack on the mixed individual for acknowledging their mixtures. This is seen in the attitudes toward mixed race people and the black community. There would be none, except if the black community began to have hatred toward the multiracial community. That's happening now without the category.
Multiracial people have similar struggles and issues that are particular to their race.
Caucasians in America are from various national and cultural heritages, including black and more recently Asian ancestry, which comes from intermixing and assimiliation into 'white' culture. What classifies them as white is their skin color, hair and eyes, not ancestry, which can be debated. The struggle of a 'white' person in America is unlike any other group including in Europe. The issues for whites in America may be completely different from their counterparts across the ocean. Just as blacks in America are genetically made up of various races from numerous nations in Africa, ethnic whites, Native American, and Asian.
