Wait, the last time you played HH was over a year or two ago and you're only commenting now?
Anyway, I will only address two points for now until I know you are willing to have a discussion about intentions and what you misunderstood. If you believe you are ultimately and objectively correct, well, you've already stated your perspective. That's all that needs to be said.
But since you commented this, I'm assuming you're open to a discussion.
1. You called someone whose only character is to support slavery, be a bigot, and someone for everyone to laugh at, as being the only person who recognizes nuance. You're basically watching Herbet from Family Guy and saying "Well he's the only person with a nuanced perspective on pedophilia." No, these are bad people with bad beliefs used for comic relief. If you truly relate to the ideals of the characters I've written to be horrible people, you may need to do some reflection. Just my opinion though.
The "Caucasians" (specifically the colonists, who were not all white by the way) of this game took direct inspiration from the colonists of america, australia, and south africa. Colonists in HH are acting like colonists in the real world. They are not "Acting like muslims or africans"
2. The protagonists are not supporting a nationalist party of elves. The nationalist movement of elves would be the High Elves, who hold the same beliefs of these colonists, but for elves. Elvish superiority over human superiority. The thing is, they're also your enemy. They're also the bad guys. They would enslave humans if they could. Nia even started with some idea that humans are lesser beings because of what they did to her, but after getting to know you, she adopts Lin's ideals of equality and equity over ultra-nationalism. Lin doesn't even believe borders should exist. So how you got to the conclusion that the player and the harem are supporting an elvish nationalist movement really boggles my mind. There are no "past mistakes of the elves." They didn't do much except defend themselves from invaders (colonists). But look, if you're just a patriot, and you enjoy your community and its people, that's awesome! That's not nationalism though.
Elves are also not a race of humanity. You can think of them sort of as we see homo-erectus or neanderthals. Elves would be homo-sylius. A separate but equal genome of the homo genus with enough differences to be considered separate species. Humans (not just "caucasians") are doing the same to elves as humans did to neanderthals. Kill, rape, merge. (This isn't shown in game, but is implied to have happened)
I am not breaking the 4th wall by criticizing ultra-nationalism, that's not what that means, by definition. You've essentially stated that because Bob's Burgers has burgers in it, it broke the 4th wall. Both things can exist in fiction and reality. The purpose of the criticism of ultra-nationalism is to make you think and possibly offer you a different perspective.
World history and geopolitics are massive interests of mine and it shows in game. The idea of a "nation" only took prominent hold in our world because of Germany in WW1 (A precursor being Napleon's French Empire.) Nationalism is a very new ideology and one I critique a lot, but specifically ultra-nationalism. In short they promoted the idea that specific people belong to their nation over the idea of a community of people working together, and that the people who do not belong to the nation should leave so that there are more opportunities for the nation's people. In Harem Hotel, this means working elves until they're dead and extinct, even though it was their land to begin with.
(I'm leaving a lot of nuance out in these comments for the sake of simplicity and time)
But no, I will not apologize for making fun of bigots and anyone who supports slavery. I will continue to mock and laugh at fascists because its the least they deserve.
I even run a Cornwall parody twitter account, which mocks Trump. It's the funniest shit ever.
