Dr. Alveda King, niece of Dr. Martin Luther King, Jr., believes the NAACP has joined gay marriage activists in an unholy alliance.

King, a 61-year-old full-time pastoral associate of African-America outreach for Priests for Life, a Roman Catholic anti-choice group, recorded a radio commercial for the Maryland Marriage Alliance, the group working to repeal Maryland's gay marriage law approved by lawmakers.

In the 60-second ad, King knocks the NAACP's May endorsement of marriage equality.

“As a minister, I believe that the NAACP leadership and gay rights activists have formed an unholy alliance by trying to convince you and me that marriage should be redefined.”

“We did not define marriage and we cannot redefine marriage,” she says, then adds: “Marriage by definition is a holy union between one man and one woman.”

King goes on to repeat what has become the group's mantra: “Gay and lesbian couples already have rights under Maryland law like priority hospital visitation, sharing property, tax exemptions, adoption, and the list goes on.”

“I believe that we are on the right side of history and the right side of eternity,” she says. (The video is embedded on this page. Visit our video library for more videos.)
