This discussion is interesting. It's something DW and I have talked about many times in the past while daydreaming of where we might live post ER.
My wife and daughter are Asian and I'm white. For the past 20+ years and all of our daughter's childhood we lived in Hawaii where white people are a minority. Our daughter's elementary school class was about 50/50 white/non white kids. In 2016 we lived for a semester in a neighborhood where I was one of only a small handful of whites.
Before we married, my wife lived for about a decade on the U.S. Mainland, first in Boston and then in Texas, where she says she experienced occasional nasty comments but generally people were, at least superficially, nice to her. She refers to people in TX as being "southern nice."
Right now, post FIRE, we're slow traveling around Asia, where I am again in the minority. Some day, we'll probably go back to the US, but we haven't yet decided where we'll live. I liked Hawaii and really don't mind being outnumbered by non-whites. Mostly people are nice to me even though I'm white. Interestingly, my wife expressed last night when we talked about it, that at some point it might be good for our daughter to be exposed to a little more "diversity" by living in a majority white small town somewhere in the U.S. DW said she thought that experience had been good for her as a young adult and might be a good learning experience for our daughter as well. I'm still a little skeptical. Somehow, I'd rather be the one getting discriminated against rather than my little girl...
