Do we have a right to choose our racial identity or sex? For example, if a person's biological parents are white, can that person say he or she is black? If someone is born male, can he demand to be known as a woman?

American Bruce Jenner recently completed a series of treatments to become a woman. Many people supported the former Olympic star's decision to change sexes. But people reacted differently to a rights activist who said she was black. She was forced to resign from her job when her mother and father admitted they are white.

Many question Dolezal's race identity

Until this week, Rachel Dolezal led the Spokane, Washington office of the NAACP, the National Association for the Advancement of Colored People. Ms. Dolezal resigned because she made others believe she is a black woman. Yet she is biologically white. She told NBC News that she has identified as a black person ever since she was a child.

"I would say about five years old, I was drawing self-portraits with the brown crayon instead of the peach crayon and the black curly hair, you know, that was how I wasportraying myself."

Ms. Dolezal's parents legally adopted black children. She was raised with them. Ms. Dolezal married a black man and has two sons from the marriage. She teaches classes about African-American culture at a college in Washington State. And she has changed her appearance to make herself look more like an African-American.

The discovery that she is biologically white has angered many people. They believe she has unfairly received help because she led others to believe she is black.

Greg Carr is the chairman of Afro-American studies at Howard University in Washington, DC.

"Ms. Dolezal -- to use some of the parlance of scholars here in the United States -- seems to have acquired everything from blackness but the burden. The story is that now -- now -- her whiteness threatens the authenticity that she may haveconstructed in her own life."

More acceptance for Jenner's change of sex

Bruce Jenner was a star of the 1976 Olympics. He has been married three times and has six children. Earlier this year, he completed his physical transformation from a man to a woman. Jenner now identifies as a woman. Her new name is Caitlyn Jenner. Most people have supported this change of identity.

Anne Morning is a professor of sociology at New York University. She says both Ms. Jenner and Ms. Dolezal will face criticism.

"They both have to deal with people who run right into conflict with our long-held beliefs about what natural real categories are when it comes to race or when it comes to gender."

Ms. Dolezal told NBC News she believes people should have the right to choose their identity.

"The discussion is really about what it is to be human and I hope that can really drive at the core of definitions of race, ethnicity, culture, self-determination, personal agency and ultimately empowerment."

Ms. Jenner's case seems to be a sign of growing acceptance in the United States that people should be permitted to change their gender. But the case of Rachel Dolezal seems to show that not as many people believe we should be able to choose our racial identity.
