When I was a child, there were considerable Chinese and Japanese communities in our area. I don't recall that they ever caused problems. In fact, they seemed to assimilate into American culture fairly well, while keeping certain aspects of their Asian cultures. For instance, they were Buddhists... members of a genuinely peaceful religion.
I should note that this was almost 50 years ago, and the Chinese were pre-PRC immigrants and their descendants.
I suggest you take a look at Hawaii today. And I might add that my son-in-law’s mother is Japanese and she was born in an internment camp. Also, FWIW, his mother doesn’t think much of ethnic Japanese either, because despite what this country did to her family, she’s an AMERICAN!
