Race Relations

Here in America, we classify everybody by skin color, by "race." But what is it really? Upon reading Mixed Blood, I came to terms with the fact hat depending on where one lives, they may be a different "race" entirely. "Race" is not biological, it is a classification depending on where exactly a person is at the moment.
In America for example, race is based on one's skin color, not including their hair, their eyes, their nose, their lips, just solely their skin color. Why is that? Why is it that I'm white and your black and he's Asian and she's Hispanic? What if my mom was Hispanic, my dad was Black, my grandpa was Phillipino, well hey now they have a new term for that too, multiracial. So many prejudices have been made based on "race," so many judgments have been made based on a social classification. How do we end this? How do we put a stop to limiting the way we view other humans, just that, humans. No white, no black, no Asian, no Hispanic, no nothing, just human. We all have vast differences and are so similar that rather than judging one another in a negative manner for something as simple as our skin color, we should just come to understand what's underneath it all.
