I can see that nuance, but the way I grew up (90s,00s,USA,minority), I do not equate the use of the word “racist” as needing to describe an act of prejudice, because I do not think it’s useful. The aforementioned joke relies on certain stereotypes of a race, making it a racist joke.

I know times change, but when I was a kid, it was okay to make racist jokes as long as it was not mean spirited. We joked about all races, but the point was alway that it was a joke, similar to jokes of stereotypes about other characteristics of people.

Edit: Then again, I acknowledge that language/culture are in constant flux, and maybe I should use “racial joke” instead of “racist joke” if I want to convey my thoughts to the largest number of people and have them interpret it properly? Or it can be accompanied by paragraphs of explanations.
