The Hawaiian Kingdom was not a race based empire. It was/is a multiracial constitutional monarchy that had much more freedoms than the US republic during the same time period.
In order to have a comprehensive discussion on this topic, I think you need to study the constitutions of the Hawaiian Kingdom and double check what information that has been told to you about its history. I think you will be amazed to see what the Hawaiian nation was able to achieve by being a neutral country in the Pacific. 
Funny you should allege that.
I worked at Keck Observatory for nearly ten years.
I had the misfortune to deal with the racial BS that Mauna Kea
seems to bring out in Hawaiians.
Their racist shit sucked then as it does now.
Your empire is not much better than Baltimore or Chicago gang banger's
Hawaii has a rich culture and what you modern racialists have done with it is
pretty shitty.
Hawaiians were and still are mis-treated.
but their "Empire" restored is not their solution.
Join the twenty second century and get rich.
or stay in the 16th and starve.
