USC business communications professor Greg Patton was replaced after he used Chinese as an example for pause words that are used in many languages. Phonetically written, the Chinese "Um, um" is "ne ga ne ga", and The Black MBA Candidates Class of 2022 complained to the school, which then removed the professor. Despite counter-protest letters signed by many other students, including many Chinese alumni, who state that the normal usage of the Chinese language should not be viewed as a pejorative, the professor was not reinstated.
