I have to tread incredibly carefully, because if I express frustration, anger or exasperation at their refusal to understand, they will tap into their pre-subscribed racist tropes about angry black people who are a threat to them and their safety. It’s very likely that they’ll then paint me as a bully or an abuser. It’s also likely that their white friends will rally round them, rewrite history and make the lies the truth. Trying to engage with them and navigate their racism is not worth that.
