The Rev. Al Sharpton, president of the National Action Network, writes in a piece for the Huffington Post that the worst thing we could possibly do after coming together around Trayvon Martin's killing and the Tulsa, Okla., shootings would be to walk away and do nothing.

Most young people today have studied the stories of the great civil rights struggle in this country and the heroic acts of many from all walks of life that eventually brought about change in America. While older generations may recall segregation or the disturbing days of water hoses and police dogs, young kids today for the most part haven't experienced open violence at the hands of bigots. Even though racial inequality clearly exists, they have been lucky to grow up in an integrated society that grows increasingly diverse by the day. So when news of the Trayvon Martin shooting first broke, it was no surprise that it sent shockwaves among our youth — and continues to do so today.

To add to the troubling climate, over the weekend, three black adults were shot to death and two were wounded at the hands of white gunmen who have since confessed to the horrific act in Tulsa, Oklahoma. Though not officially ruled racially motivated yet, this latest incident has all the underpinnings of a despicable hate crime. It's no wonder young people have taken to the streets to march, organize and let their voices be heard. We are at a precarious moment. We must stop ourselves from regressing. We cannot allow our future to be hijacked with hate. We need not a moment, but a true movement immediately.
