Answer: Not exactly.
Explanation: No, I wouldn't say people are only complete when they're aware of their ancestral culture. Many people have no idea who their great great great grandma was, or even know she existed. I think a lot of people are focused on the now, and either don't have time, or just wouldn't like knowing. It is a very good thing to be proud of your culture, and where you've come from, but it is not a necessity. You don't need to embrace your culture, or race, to be confident and proud of who you are.
