It’s worth noting that the Kamehameha Kingdom “unified” the islands in the same manner that the US did, just with less advanced weapons. They were outsiders to Hawaii & “invaded” too. I’m not justifying the situation & put a lot of consideration(months) into the history/etc. before moving here.
All my experience with locals suggests you are VERY welcome to visit but they do prefer that you’d not move here Visitors are the life-blood of the economy, after government-jobs & military bases. With the exception of a few islands, I should add. Molokai is said to be unfriendly to those not invited by locals, Lanai is privately owned by Larry Ellison, Niihau is also by invitation only & privately owned, & Kahoolawe, the former bombing target of the Navy, is also restricted.
