(CNN) – Ezra Dolezal would love to see his sister, Rachel, take a DNA test to prove whose version of the truth about her racial identity is the right one.
But he doesn’t think she will.
Rachel Dolezal has gone from a Spokane, Washington, activist to the focus of a highly charged national debate in recent days, after reports surfaced that she was born white yet has claimed she is black. Amid the controversy, she resigned Monday as head of her local NAACP chapter and, a day later, spoke out extensively for the first time in an interview with NBC.
And she didn’t back down when it comes how she sees herself, even after her parents shared childhood photos of a young Rachel Dolezal — her pale complexion and straight blond hair in contrast to the woman with darker skin and dark curly hair who appeared on NBC.
For the family, one comment stung especially hard. “I haven’t had a DNA test,” Dolezal said. “There’s been no biological proof that Larry and Ruthanne are my biological parents.”
