На русском Вам разъяснили, would you like to have it in English?

Prejudice - An unfavorable opinion formed against a person or group based on a stereotype.
Stereotyping often results from, and leads to, prejudice and bigotry.

Unchecked prejudice and bigotry leads to discrimination, violence, and, in extreme cases, genocide. Prejudice can be spread by the use of propaganda and inflamed by demagogues.
Language, particularly slang, is often used to dehumanize members of certain groups of people, and this dehumanization is a precursor of discrimination, isolation, and violence. Which way?
The answers can be found by understanding how violence of this magnitude can evolve out of prejudice based on ignorance, fear, and misunderstanding about minority groups and other groups who are different from ourselves. A "stereotype" is a generalization about a person or group of persons. We develop stereotypes when we are unable or unwilling to obtain all of the information we would need to make fair judgments about people or situations. In the absence of the "total picture," stereotypes in many cases allow us to "fill in the blanks." Our society often innocently creates and perpetuates stereotypes, but these stereotypes often lead to unfair discrimination and persecution when the stereotype is unfavorable.
Television, books, comic strips, and movies are all abundant sources of stereotyped characters. For much of its history, the movie industry portrayed African-Americans as being unintelligent, lazy, or violence-prone. As a result of viewing these stereotyped pictures of African-Americans, for example, prejudice against African-Americans has been encouraged. In the same way, physically attractive women have been and continue to be portrayed as unintelligent or unintellectual and sexually promiscuous.
Stereotypes also evolve out of fear of persons from minority groups. For example, many people have the view of a person with mental illness as someone who is violence-prone. This conflicts with statistical data, which indicate that persons with mental illness tend to be no more prone to violence than the general population. Perhaps the few, but well-publicized, isolated cases of mentally ill persons going on rampages have planted the seed of this myth about these persons. This may be how some stereotypes developed in the first place; a series of isolated behaviors by a member of a group which was unfairly generalized to be viewed as a character of all members of that group.
Understanding the nature of prejudice, scapegoating, stereotypes, and discrimination is the first step in combating these practices. All of us have prejudices about members of groups different from ourselves. We should, however, recognize that we are not acting fairly if we treat people differently because of these stereotypes and prejudices. Each one of us deserves to be considered a unique human being.

По-моему, фраза о том, что предрассудки не могут быть истреблены, потому что слишком глубоко укоренились в человеческой натуре, не требует особого объяснения, т. к. здесь само предложение есть ответ на вопрос. Если же хочется дискуссии по поводу того, почему же они так глубоко укоренились - это другое дело.
