The idiotic practice of lumping Chinese, Indian, and Indonesian people together as “Asians”, as if the term had any kind of cultural relevance, is mainly a tic of journalists. For the most part, normal people don’t talk or think this way.
My girlfriend's mom is Cambodian with Chinese ancestry. One time she was describing a pickled cabbage preparation from her home village, and I responded with "oh, so kind of like Korean kimchi?" and her response was "yeah, but Asian-style."
In her mind, "Asia" specifically means China, Vietnam, Cambodia, Laos, Burma, and Thailand.
African as a label becomes even stranger when mixed with American. African-American is usually used as a synonym for Black American, despite not all Africans being Black. An Egyptian-American likely would not be called African-American.
We use words weirdly!
