I agree with MayasMother that kids do want to be like the other kids around them often regardless of what it is. But I still think here could be some racial identity issues wrapped up in it well though. I know my son is not sure where he belongs at times, and I hear this a lot from multi-ethnic/cultural families, parents and kids.
My 8 year old sister is going through similar issues, and we call it the "me toos." wants what everyone else has, and she wants to act, look and talk like her friends.
I try to counteract the thoughts by talking about my son's (and my sister's) traits positively and as unique special features. I explain that they are part of his parents, and he is just like us--but a special mix. How he is perfect because of who he is. I constantly send these messages to him, and he seems to be more comfortable being who he is rather than wanting to be like people around him for the most part. It's not a perfect solution, but it does mitigate the issue at times.
