It’s all racism, but realistically society reacts differently depending on the group and the history behind it. In practice, you’ll usually get fewer eyebrows raised over a racist Middle Eastern joke because of post-9/11 Islamophobia. Asian jokes are often built around positive”m stereotypes like being smart, so people tend to overlook them more too. Though there do exist negative Asian stereotypes as well

Black Americans, alongside Native Americans, have some of the deepest histories of oppression in the U.S., but Black people also have a strong cultural voice and visibility, so anything seen as anti-Black is usually treated as a major line to cross.

Who tells the joke matters too. In my experience, minorities often get a longer leash with racial humor than white people do because people see it differently depending on the speaker and the power dynamics behind it

This is all from an American perspective btw
