Rachel Dolezal:

(CNN)What would be the problems inherent with someone misrepresenting their race, even if that person spent a career advocating for the race that he or she falsely claimed to be?

And at what point can a person ever legitimately choose to belong to a race with which they have no apparent genetic connection?

Social media exploded with reaction Thursday and Friday to allegations that Rachel Dolezal, the head of a NAACP chapter in Washington state, is Caucasian but has been misidentifying herself as at least part African-American.

Dolezal, whose biography says she attended the historically black Howard University, also teaches African-American studies at Eastern Washington University and serves on Spokane's independent citizen police ombudsman commission. CNN's attempts to reach her for comment have been unsuccessful.

Here's a sampling of the reactions that made #RachelDolezal and #transracial trending Twitter topics Thursday morning:

She look black to me
