Step-by-step explanation:
America struggles with its identity today through various factors that shape its culture and society. The country's diverse population, multicultural sensibility, and tolerance of diversity have led to conflicting political identities that challenge Americans' sense of who they are. Additionally, the changing construction of whiteness and the disconnection between lived experience of race and ethnicity and government classification further complicate the understanding of identity in the twenty-first century. These challenges contribute to America's ongoing struggle to create and define its national identity.
