Vikki [24]

Answer:

the classification of racial types is an arbitrary, culturally specific process.

Explanation:

Racism can be defined as an act, practice or policy by an individual, group of people or institutions which typically involves promoting the ideas and belief that a race is superior in comparison with another. Thus, it simply means the believe that a particular race has dominance over another (an inferior race).

An examination of the classifications of races from around the world indicates that the classification of racial types such as Africans, Americans, Indians, Asians, Black-Americans, Hispanics, etc., is typically based on individual perception, not objective and an impulsive (arbitrary), culturally inclined or specific process.

This ultimately implies that, the classification of racial types is considered not to be based on any form of objective distinction but may be defined by a person's culture.

A culture can be defined as the general way of life of a group of people living together in a particular location or society.

Basically, culture comprises of beliefs, values, behaviors, language, dressing, cuisine, music, symbols, arts, social habits, knowledge, customs, laws pertaining to a particular group of people living together in a society.
