In the article, it says that the kids were doing an exercise where they closed their eyes, and anyone who had experienced racial trauma was asked to raise their hand. She interrupted in the moment commenting that it was only “part of the room,” and the students started looking around irritated, saying things like “what does it matter if it was only 10 people, I raised my hand”. I’m not commenting on the veracity of any of this, just telling you what the article itself said.
