Your knowledge of historical facts is very basic, to put it mildly. The African slave traders you were mentioning kidnapped Dr Dolittle, Conan Doyle, Jack the Ripper and the English Queen to eat them up. They were not interested in ordinary villagers from the English coast because they did not taste too well as they had too much of the stinky fish and chips odour on them. These African slave traders came all from highly civilised nations where cannibalism remained just as a relic of their less civilised past. Why ignoring or denying these hard historical facts? You know them, and everybody does. You should also teach your Chinese students these points of glorious English history.
