You don't have to be multicultural to stay in touch with your roots. My American family is mutiracial, but not multicultural. European, Korean, African, and Jew are all there, via adoption. All of my adopted siblings had to adjust to our culture and language. But at the same time, my parents encouraged them to learn about their individual heritages if they wanted to. I believe that our family represents what is unique about America as a whole: we speak a common language and live a common culture, but are proud of our individual heritages.
