How does Pride and Prejudice relate to the theme of intolerance?

The subject of prejudice is linked to pride in the title of Pride and Prejudice. It is also more directly linked to Elizabeth Bennet's character From the beginning, Elizabeth sets herself up as an ironic spectator, able and prepared to judge and classify people as either simple (shallow), intricate, or those who cannot be judged and classified so easily..... 'the most amusing'. Elizabeth is prepared to divide the entire world into one of these two categories—an extreme example of prejudice in the "pre-judging" sense of the term. This is most evident in her judgment of Darcy, so sure is she of her powers of observation that she refuses to reevaluate Darcy even when the weight of evidence begins to turn in favor of him.

It is not until Darcy overcomes his own prejudice against those of lower social station—by treating Elizabeth and the Gardiners graciously and considerately at Netherfield—that Elizabeth's opinion of him begins to change. "Not only do Elizabeth and Darcy... have the most serious problem of surmounting barriers of misconception and adverse feeling," Heilman declares, "but they are the most sensitive—both in susceptibility to injured feelings and in capacity for getting to the center of things—to matters of prejudice and pride" The ending "is a remarkable tracing of Elizabeth's coming around to a completely changed point of view," the critic concludes. "To Jane she acknowledges that she has cultivated her 'prejudices' and has been 'weak and vain and nonsensical.'" With this realization Elizabeth begins the process of change.
