The social-conflict approach is the "framework for building theory that sees society as an arena of inequality that generates conflict and change". Using the social-conflict approach, we can examine the "conflict between dominant and disadvantaged categories of people, such as the white people in relation to people of color". At a gun shop, a Persian-immigrant, Farhad, and his adult daughter, Dorri, are discussing, in a foreign language, what kind of gun to buy. The frustrated owner interrupts them saying, "Yo, Osama! Plan a jihad on your own time. Your liberating my country and I'm flying 747's into your mud huts and incinerating your friends," and he proceeded to have security remove Farhad. The stigmata, "a powerfully negative label that greatly changes a person's self-concept and social identity", that are against any olive-colored skinned person, came post-September 11, 2001 after the terrorist attacks. Stigmata's are surrounded by prejudice, discrimination, and stereotypes, that can cause one to become socially isolate if they start believing in them such as the Thomas theory states.
