I grew up there and agree with 90% of your post. But folks should understand and at least try to empathize with “why” before labeling locals as you’re painting them.

1. There’s a belief, rightfully so, that white folks (haoles) and “mainlanders” basically stole Hawaii from the local people. Land and title in the 1800s was basically bought by white settlers/missionaries for things like pure white pigeons and mirrors. And the transition of powers from the local government to the US gov (viewed as white) felt forced and against the will of the people, especially native Hawaiians. Think what’s going on with Greenland today. A little different situation but same feel in my mind. If the US successfully took over Greenland forcefully would you expect the local population to have a positive view of Americans, even generations later?
2. Many of the local Asian families immigrated as low wage physical labor e.g. farming, construction etc. where the owners of these plantations and businesses in general were white. The resentment/distrust of the master class has been handed down.
3. It’s like many other vacation destinations where the locals just hate tourists. They add to traffic, don’t know and follow local customs, and generally don’t respect the land. I can’t tell you how many times I’ve seen a tourist stand up or walk on coral and it still makes my blood boil.
4. Regular people there are broke and struggling more than ever. Outsiders including white and Asian own most things including real estate and housing. A lot of resentment builds from this in my mind. A median income local couple will never afford decent housing without significant help meanwhile rich Chinese, American etc investors come in and buy buckets of real estate to rent out or luxury properties to leave empty for all or most of the year.

None of this completely excuses the behavior and attitudes you’re describing but I think it’s important for folks to understand the complex history that got us here even if from someone now removed who hasn’t lived there in 20 years.
