I will first explain the SOCIAL LOCATION of the three characters found in this scene. Firstly the Persian man, Farhad, looks aged and is clearly a male relative to the Persian lady. He is able to speak English, although with a strong accent and broken grammar. He speaks Farsi only to his daughter despite being in an English speaking environment. Therefore I could infer that he is a Persian immigrant who has settled down in the US.
The Persian lady, Dorri, is the daughter of Farhad; she speaks English fluently with an American accent, is not dressed in stereotypical Middle-Eastern attire, and she is young. I could infer that she may have been born in the US or brought to the US at an early age and is probably recognized as a young Persian-American woman.
The Caucasian man on the other hand is an example of a bad stereotype of the patriotic, white, American man. Firstly, he owns a gun store (the stereotype that men like him have a bold interest in the right to firearms), he is sexist (in his remarks about the different fitting bullets to Dorri), and he is also very racist and patriotic (he accuses Farhad of planning terrorism and references September 11).
In these scene it is clear that the person with POWER is the gun store owner, he abuses this POWER by first accusing Farhad of being a terrorist, something that Farhad does not take kindly too. Despite Farhad's valid rebuttal that he is an American citizen with just as much rights as the owner, the owner refuses to acknowledge and instead calls on security, who happens to a Caucasian man too. Farhad exits the scene stubbornly, and Dorri is left with the owner. She speaks to him in American English to demonstrate her "American-ness", in an attempt to avoid the same problem her father had. However, much to her chagrin, she realizes that the owner further abuses his POWER by degrading her as a woman. He sexually harasses her knowing that she does not have any POWER in his shop. Therefore this scene is a good analogy for the OPPRESSION felt by Middle-Easterners who are subject to accusations by Americans, and women who are subject to sexual harassment.
The second part of the clip introduces four main characters and one unseen character, two African-American UCLA students, a Caucasian couple, and an African-American waitress.
The two UCLA students are young African-American men. They were in a restaurant eating spaghetti, after waiting half an hour, and were served by a black waitress. They do not dress in the stereotypical gang fashion, nor do they have any visible tattoos, and they attend UCLA. I would infer that they are university attending African-Americans with nothing to do with gangs.
The black waitress, while unseen, is described by one of the young men as having sized them up before even serving them. Described as intentionally giving bad service to them on the grounds of African-American stereotypes.
The Caucasian couple consists of a well to do looking man and woman. Dressed well, the couple are arguing over the man's phone conversation with another woman. The woman is depicted as somewhat jealous while the man is depicted as a figure of strength and above pettiness. I would infer that these two are the…
