The question I would ask in response is this:

- What evidence do you have that "teaching children that are personally guilty of slavery" is something that actually happens?

We are all related. Both you and I, along with many others, feel a deep empathy for his untimely passing. If we compared notes that I suspect that we would both agree that using tragedy as a political soapbox to score political points is wrong. Speaking up when that happens is the moral imperative. That is especially true when what happened is misrepresented and distorted. We honour him by being conscious of the truth, the facts, by refusing to permit his life to be politicalised, and calling out those that are doing it.
