Final answer:
Rodriguez's point is to emphasize the different experiences of ethnic identity in Mexico compared to the United States.
Step-by-step explanation:
Rodriguez's point through the anecdote of the girl who identifies herself as 'Blaxican' is to emphasize the different experiences of ethnic identity in Mexico compared to the United States.
In Mexico, there is a higher rate of intermarriage between Europeans, Native Americans, and Africans, leading to a more mixed and cohesive Mexican identity and culture.
On the other hand, the United States has a more diverse population with multiple ethnicities, which can result in more fragmentation and challenges in managing ethnic differences.
