Mixed Blood

It's really beginning to bother me that Obama is listed as African-American and no one seems to acknowledge his white heritage. They the Obama's are preparing to celebrate black music at the white house a it seems only blacks will be entertaining - although many black musicians admit they have been influenced by white artists in the music industry. I too am mixed blood white and Native-American, and while I understand the difficulties experienced by the black cullture; I question why persons of mixed blood are taught to surpress their cultural heritage until it suits them to disclose it.
I recently did a composite of drawings of Martin Luther King for students at the College I am attending, yet I was excluded from the actual Martin Luther King celebration on the day designated for him. I can only believe I was excluded because I appear to be white. I find this hurtful, yet as my Native heritage has taught me I must be inclusive of all. When our constitutional forefathers created this country it was WE the people, not just African-American, Native-American, Mexican-American, Orential-American, or Caucasian. Why can't we embrace our freedoms with out labels?
