Abolish the act of Ethnicity in the United States and become one classification know as "Humans"

We The People of the United States Must realize that it is time to grow up and get rid of being call ethnicity. We may have different colors but we have to realize that this country has come from different countries to become one. Yes we do get offended when it comes to getting called by racial names but we must think that if other people were called a different word then soon it adapts and would be considered a racial slur. Eventually if the possibly of other life forms from this planet then they will be judge on the based of different form. The Obama Administration should blank out the term "ethnicity" Because the big questions are though: why are we here? Where are we from? Where are we going? But if ignorant people are in the way we will never figure out the answer to those questions.
