Quote #10
At the Atlanta station we waited for the whites to get off. One of them, a large middle-aged man, hesitated, turned and stepped back toward us. We hardened ourselves for another insult. He bent over to speak to the young Negro. "I just wanted to tell you that before he slapped you, he'd have had to slap me down first," he said. None of us smiled. We wondered why he had not spoken up while whites were still on the bus. […] "Well, I just wanted you to know—I was on your side, boy." He winked, never realizing how he had revealed himself to us by calling our companion by the hated name of "boy." We nodded wearily in response to his parting nod. (20.65)
We have another word to add to your list of racism related vocabulary: infantilization. That's when you reduce someone to the same status as a child or a baby. That's what this guy is doing by calling the black man "boy."
