in recognition of black history month, tonight's brief but spectacular comes from historian daina rameyistory department at the university of texas at austin. she's dedicated to rethinking the way we teach american history to students of all ages. her latest book is called "a black women's story of the united states." >> i have a son who's now in his teen years. his first racial experience was at age three. we had just moved to austin, texas, and we ran a neighborhood meeting about the community we were in. we were the only black family that were there. my son comes downstairs at three years old, and he was pouting. i said, what's wrong, honey? he said, they told me i had to be the bad guy because i'm black. and he said, and i want to be the good guy. i want to be the hero. and i want to be the one that saves people. the mothers were frozen. they didn't even know what to say. it was totally uncomfortable for me after that. i didn't want to leave the meeting, because i wanted my son to know that we're going to stand there and we're going to still be there and that he can be who he wants
