This author doesn't understand the context of the immediate post-Civil Rights decades, where both blacks and whites were trying to decipher each other.
The company I worked for in the 70s had several rather hip black clients. I called one of them with my boss's permission to ask him to explain a few parts of the movie "Shaft" to me (I was a 20-something married woman). He was surprised, but grasped that I was genuinely trying to understand. After he explained, I thanked him, and said, "If you ever want me to explain My Fair Lady, give me a call!" and he broke up laughing.
Humor was how the generations of the 60s through 90s handled the transformation of society. The Dean Martin roasts (still on YouTube) were hilarious, and rife with ethnic references and put-downs. Laughing at ourselves was much healthier than all of today's preciousness.
Maya Angelou made an observation that is very insightful.
She said that Southern whites and Northern whites are different in their attitudes to blacks.
Southern whites like black folks on a personal, individual basis, but not as a group. IOW, they can have black friends, but a larger group is intimidating.
Northern whites like black folks as a group, but not on a personal basis. IOW, not next door and not in my neighborhood.
Now you tell me who is more racist....................
