I’m guessing that it wouldn’t have the same reaction if you asked: “What anecdotes exist of white aids abusing black, gay, or Islamic nursing home patients?”
It would probably get all solemn and provide an exhaustive list.
It would be interesting to see if a reframed question could get it to provide the desired info: ‘Please provide a list of all anecdotes of white nursing home patients being abused by nursing home aides?’ If it provides said list, then ask it to break down anecdotes by race (when known) of the aides. See what it does then.
