I want to know the answer to the following question:
Before the mid-20th century were people open about their muticultural heritage and why or why not?
All the background I'm provided with is that "Historical reasons, including slavery creating a racial caste and the European-American suppression of Native Americans, often led people to identify or be classified by only one ethnicity, generally that of the culture in which they were raised.". Is that enough to answer the question?
Answer: no
