I'd say most white people have seen and heard many black women in their lives some of which they probably had a crush on like Halle Berry, Whitney Houston, and Vanessa Williams. What about Aretha Franklin and Ella Fitzgerald? How about Oprah? We were exposed to many awesome African American women well before Michelle came along.
What Michelle Obama wrote was disgusting and very much offended me. It was demeaning. It's yet another reminder based on several things both Obamas have said in the past, that they helped divide our country well before Trump came along.
