I've noticed that racial identity is very important to many black Americans. I found this very interesting article:
"The social identity of individuals is linked to their racial and cultural identities which give them a sense of purpose in life. It is common knowledge that Italians, Greeks, Russians, Germans, French, Swedes, Finns, Norwegians, Spaniards, to name a few, have identifiable cultures that are linked to their social and racial identity and that this identity is embraced, welcomed, and accepted throughout the Western world." Etc.
If racial identity is psychologically (and socially) important, then could racial confusion be psychologically damaging?
