Source: IANS Amid the growing diversity debate over this year's Oscar nominations, Oscar and Grammy Award-winning musician John Legend has urged his fellow artistes to stand up and use their voice to fight for racial equality in the US while picking up the NAACP President's Award. The artiste delivered the emotional speech on racism while accepting the honour at the NAACP Image Awards on Friday night, reports thedailybeast.com. "We know that we stand on the shoulders of giants who risked their lives to bring us closer to true freedom. And of course, we are still fighting for freedom," he began moments after singer Alice Smith delivered a powerful rendition of 'Glory' - his Oscar-winning 'Selma' song - with hip-hop artiste Common. The singer, who also performed his hit song 'Ordinary people' at the annual gala, added: "Today, communities of colour are still being crushed by a criminal justice system that over-polices us, over-arrests us, over-incarcerates us, and disproportionately takes the lives of our young people because of the simple fact that our skin conjures the image of threat and violence."
