I think this is the correct response though, it's absurd and a symptom of how these generative models work.
The discussion should highlight for people that these models can be, and often turns are, wrong. There's not a mechanism to verify factuality or accuracy, and you shouldn't expect as much.
Instead, this group of people go into the ol playbook and pull out "wow, minorities are being forced on me again!" Generating these silly conspiracies and manufactured outrage.
Chill, it's funny, laugh. Seeing minorities in something shouldnt be the reason (or the example) for outrage.
It's a real challenge. The datasets all have genuine bias built in and identifying and correcting it is incredibly difficult. I mean, there WERE people of color in historic Europe, lots of them. So you can't correct this by just making them all white because that isn't necessarily more accurate. But yeah, we know that King George wasn't black.
