A few examples from the Chinese half of my family/history.
The generation before me had to use the colored community pool, and were the only Asians in their Catholic schools growing up.
This century, in states on the southern border, relatives were pulled over and asked for papers please because they looked Hispanic.
I’ve personally been mocked as yellow, communist, chink, chinaman, a-Shen (a pun on my name), why-you-no-doctor-yet, why don’t you go back to the paddies, sweatshops, how can you see out of those things (and my eyes aren’t even that slanted), etc. I’ve heard a few slurs against Hispanics directed at me. Oh, and people sometimes think I speak Chinese or Japanese or Anime (which might as well be a different language).
When I’m the only asian around, I might feel like I’m representing asians as a race. People will ask me questions about why asians do X or about the history of China or U.S.-China relations like I’m some sort of expert.
Usually these sorts of things come across in a joking manner, I have thick skin and don’t personally mind it much. Sometimes the jokes are funny. In my father’s day, there was real hatred behind it.
Oh, and sometimes people on messageboards say we don’t love our children.
