There's a difference between inserting bias and allowing a real-world pattern to exist in AI. There may be reasons to dislike these real-world patterns, but that doesn't mean that allowing them to exist in AI is inserting a bias.

For example, if you ask AI to write a realistic story about an NBA team, and it comes back with a team with stereotypically Asian named players, that would be unrealistic. If it came back with a team with stereotypically Black named players, that would be fine. Does it reflect a real-world pattern? Yes. But not changing the algorithm to generate diverse names isn't inserting bias. It's letting AI reflect the real world, as it exists.
