Who gets to define your race?

Rachel Dolezal is on the talk show circuit now, still insisting she's black. Her stubbornness is challenging us to think about racial identity in new ways.

Is it something your ancestors dictate or whatever you feel in your soul? Who gets to police those boundaries? Is skin color still the defining force?

The story of Dolezal — the white civil rights activist in Spokane who's been passing for black — has sparked soul-searching and debate.

You can join that conversation in today's Times video chat at 12:30 p.m. PT, as columnist Sandy Banks, Dexter Thomas who studies and writes on race and USC law professor Camille Gear Rich talk about Dolezal's charade and the idea of "elective race" and "transracial" identity.
