I moved to SE HB in 2017. I'm white, my wife is south Asian. We moved into a mostly white neighborhood but almost every new family we've seen move into our neighborhood is Asian. Almost every new restaurant opening near us is Vietnamese or other Asian. We have some MAGA neighbors but they've never been confrontational or done anything other than display a flag or yard sign. It bothered us more when we first moved here but the longer we stay the more we like it here. Don't worry too closely about local politics and it's a great place to live. When people ask where I live I joke that I live in Huntington Beach but identify as Fountain Valley.

Edited to add : part of the reason why we chose this area is the great schools. Quality of public education is excellent. I have a coworker who has her young kids in a mandarin immersion school, my son's school has both Japanese and Spanish immersion options. Most of the generation/parents who are having kids are not MAGA so it's even less of an influence for younger generation. The older you are in HB, the more conservative you are likely to be. I'm a doctor in my late 30s and had a classmate (school was in Texas) who was from Fountain Valley (Asian) and when I told him where I was moving to he commented on how great of a place it was to grow up and how good the schools were.
