I don't have a problem believing this. Remember the sambo dinosaur from the Star Wars prequels?
It was a slur 65 million years in the making.
In Jurassic World, there's a scene in which the protagonists learn that a group of dinosaurs, called the Pachycephalosaurus, have escaped. For shorthand, they call the group of dinos "Pakis," which American audiences may not realize is an offensive slur in the U.K. — referring to people from Pakistan.
