i really think it would serve a lot of Americans well to go and spend some time in Brazil. Now this is not say that there is no racial divides in that country but moreso to demonstrate this American need to pigeonhole someone into either black or white is pretty stupid. They have words for people that are really dark complected, really light complected, dark complected with straighter hair, light complected with curly hair, medium complected in all of its spectrums with most permutations along a myriad of any features you can probably think of.
Its pretty interesting because it shows that people can be looked at as different but that humans are so diverse and unique that its a very beautiful thing.
