You were a true hero and you became an inspiration,” Wonder, 70, started. “I’ve been blessed to write songs of hope, love and motivation, many of them inspired by your life. More than any award I’ve ever received, I want you to know that I am thankful for how you influenced my place of love, which allowed me to try to push the needle of love and equality forward.”The singer then voiced his criticism of the shortage of racial equality and acknowledgment of Black folks’s reality since King’s loss of life in 1968.”It is painful to know that needle has not moved one iota,” Wonder continued. “For 36 years, we’ve had a national holiday honoring your birthday and principles, yet you would not believe the lack of progress.”RELATED: Morgan Freeman Narrates Martin Luther King Jr.’s Words to Commemorate the Late Activist’s Holiday”It makes me physically sick.
