However I have seen another bit of your logic elsewhere and strongly disagree with it: the idea that mislabelling (or even correctly labelling) something "does an injustice" or "is a disservice" or "would be offensive to" people who died in the past at the hands of someone/something. We only have an obligation to make the lives of current and future people better: people who have died because of hatred would surely appreciate us doing our best to combat hatred in the modern world.
