Stupid comment. Of course it was just made up. How do you think the term was first coined?
There are identifiable differences between any two people. Therefore there is a race for each human. There the term is meaningless.
Like I said, a different "race" for each person. Stupid.
There's no official listing of "races" I see.
Differences between individuals do not constitute a race for each person--that is ignorant.
However, there are identifiable similarities between groups of people we can use to classify.
