I remember an antiracist activist a few years back who put a video online in which he stressed that, instead of saying "you're a racist" to someone who had just done or said something racist, he would say "you just said/did a racist thing". His point was that, when he framed what he said to the person as pointing out a mistake a person had made, a mistake that person could learn from, correct, and avoid repeating, that person was much more likely to change than the person would have been if the conversation had been framed on the racism being an outright personality trait.

What do people in this comments section think of that particular approach?
