At present, the intensification of social division and the prominence of racial issues in the United States have profoundly impacted the cultural landscape of college curricula. The predicament of college curriculum culture, represented by critical race theory, has become more evident, mainly manifested in the fragmentation of the core values of curriculum culture, the implementation subjects bearing strong regulatory pressure, and the target audience encountering knowledge screening. The two parties in the United States are engaged in a debate over the inclusion of critical race theory in college curricula. The Republicans firmly oppose its introduction into American college courses, while the Democrats defend it on the grounds of democracy, freedom, fairness and justice. The changes in the curriculum culture of American colleges and universities reflect the current dilemma in reshaping the core values of the United States, which directly affects the political integration among ethnic groups and the building of cultural soft power in this multi-ethnic country. In light of this, American colleges and universities should actively promote ethnic studies courses, create a teaching environment oriented towards racial justice, and focus on improving multicultural education in the curriculum. The effectiveness of these measures will be tested in the overall situation of the country's cultural security.
