I think this quote is important for all people, especially for teenage girls. Girls can be so happy and positive, but at times we can be influenced and hurt by a number of things. People need to learn that no one else should change who you are.
What people forget is that it's not only whites who CAN be racists. It's a two way street. Just listen to the likes of AL Sharpton, Oprah Winfrey, and Obama to name but a few. They thrive on the division of people; they perpetuate racism.
