It's a sensitive topic in many countries, and for very good reason.

[eta: by "very good reason" I don't mean that it is a good thing that racial prejudice exists. I mean that people who experience discrimination and the ugliness of white privilege have every reason not to feel amused when the subject is treated as something to tell anecdotes about. It's like sexism - we may think it's dead, but it really isn't, and making fun of the way women are underprivileged just isn't amusing. This is said with the greatest respect to CE, whom I know to be a thoroughly good guy.]
