Racism is a product of prejudice and every human being has prejudiced views. If someone denies having prejudice views, it highlights his lack of self-consciousness.
Historically, racism against blacks in the United States was created to exploit them. Racism is the product of black exploitation, not its cause.
The nature of exploitation might have changed in the modern US, and it might not be visibly perceptible to white Americans, yet colour prejudice exists in the minds of Whites.
Still there is conscious and unconscious denial of racism among the whites, thereby making any effort to remove racism absolutely impossible.
