John McWhorter has changed his policy on what words to use to describe his racial group. He has used 'African American' and 'black' almost interchangeably, but now he's decided not to use 'African American' anymore and only to use 'Black'. He gives his reasons in the article why he won't use 'African American' anymore. I wonder what his reason for the change from 'b' to 'B' is. He doesn't say that. I've heard other people's, but he's a linguist, so I really want to hear his reason.
