>How do Hawaiians feel about this?
As is the case when it comes to indigenous populations being displaced and slowly replaced over time: they don't get to have a choice. Hawaii was mostly Japanese in the early 1900s having already displaced previous arrivals, and today less than 15% of the population considers themselves native hawaiians. The remaining 85% are there _because_ Hawaii is not independent, why would they ever hold a vote for it ?
