Final answer:
Maggie's behavior of feeling nervous and defensive about race discussions without understanding racial power dynamics is an example of colorblindness.
Step-by-step explanation:
Maggie's actions, being nervous around discussions of race and becoming frustrated and defensive without trying to understand how power operates within the system of race, are most closely aligned with colorblindness. This term refers to the avoidance of racial language, an idea that suggests racism is no longer an issue and hence there is no need to discuss race or acknowledge racial differences. This concept is part of a broader cultural narrative in the U.S. that tends to focus on individual racism and fails to recognize systemic racism. Maggie's discomfort and defensiveness suggest a reluctance to engage with the concept of race and the dynamics of power related to it, which is characteristic of colorblindness.
