Cultural mixing happens both ways. Sometimes inclusion means changing long standing traditions.
Have there been any natural experiments where less-wealthy white folk were priced out by more-wealthy non-white?
Cities like Fremont, Union City, Santa Clara, Sunnyvale, Cupertino were pretty much 80% white 50 years ago. They're now about 24-34%. With housing prices at $1-3M here, do you think that most of those white people went on to afford even more expensive homes elsewhere? Mostly not, they're priced out of their hometowns. You can see this in California migration patterns, where many more Americans emigrate California cheaper states than immigrate (you could consider some of them "gentrified") while CA adds population from immigrants internationally, and thus the population is steady.
Of course, it's "techies", really affluence, displacing non-techies, rather than any racial motivation.
Upon checking, it doesn't look like overall Hispanic populations are being displaced out of the Bay Area. It looks like some areas like SF and Fremont have slightly lower Hispanic populations from 2000-2018, whereas cities Hayward and San Jose increased by a further amount.
Just guess who is the be seen as the enermy, guilty of some original sin that must be attoned at all times.
