It may also be directed at beautiful or rich people regardless of color. The negative attitude could similarly be directed at an individual or an entire society. Regardless, our attitudes known as prejudices are usually not founded in reason. People who foster prejudices normally believe that they are right to have negative attitudes toward certain individuals or groups of people. Such people justify their prejudices by offering various examples to show that they are right. A white man who has visited an American jail may say that he knows that all African Americans are bad people because most of the people in jail are African Americans.
Racism which is a form of a prejudice thus intellectualizes the negative attitude of people toward people. Racism is actually defined as a belief system which states that individuals can be superior to others on the basis of race. This theory has led to much violence and genocide in the world. Still, most people have preconceived notions about other people with respect to their races. It takes a high level of education, perhaps, to believe in the essential equality of mankind.
