Kennedy doesn't understand that when she uses phrases like "people like her," she tells Ruth that she's already judging her based on what she can see. Similarly, questioning Ruth about what term she prefers is a good-faith attempt to listen, but still comes off as tone-deaf and rude. This shows how, for someone like Kennedy who doesn't think she's racist, it's actually very easy to inadvertently uphold racist systems simply by tiptoeing around the issue.
