"I have a dream that my four little children will one day live in a nation where they will not be judged by the color of their skin but by the content of their character."

So goes a part of Dr. Martin Luther King Jr.'s famous "I Have a Dream" speech that he delivered on Aug. 28, 1963.

Jan. 16 is Martin Luther King Day and as we reflect on King's life and work, it seems reasonable to ask whether we've achieved King's dream.

According to Wikipedia, "post-racial America" is "a theoretical environment where the United States is void of racial preference, discrimination, and prejudice." It sounds like the kind of place King dreamed of for his children.

So what do you think? Are we living in a post-racial America? Answer our poll and leave your thoughts in the comments.
