Do are differences define us?

Differences is extraordinarily relative considering there are 7 billion people in the world ...

Though, ultimately I believe everyone is an individual. You cannot define the characteristics of a person based from someone else who is from the same cultural/ethnic/religious group as them, if that makes any sense.

So, yes. We are unique, individual people with "differences" that mold who we are. All at the same time, we are all probably not the unique, special snowflakes we believe we are. Our differences can define us, however they can also bring us together to form our modern day society.
