What attitude of racism is foreshadowed in Part One, Chapter One?

During the get-together at Eva's house, the white guests make blatantly racist comments about Haroon, the speaker. Ironically, however, the guests are still perfectly willing to follow Haroon's lead in the guided yoga and listen to his thoughts on philosophy. Charlie is particularly wiling to listen to Haroon's thoughts, yet still ridicules his appearance. It seems that this contradictory atitude toward differences in race will be a continuing motif throughout the novel.
