Social Justice is not an American concept, unless your knowledge of history only goes back to 2016. Your usage of conservativism and everything makes me think this is the case. Most revolutionaries who fought for our freedom are "Liberals" in the global sense (not the modern American-centric sense). Liberal meaning Free. This is where the statue of "Liberty" comes from. AKA, the statue of freedom. To conserve in this case would mean to bring back the monarchies. There is so much more to history than the last 10 years of the US.
The reason we have freedom is in large due to revolutionary protestors overthrowing their governments, mostly violently. Such as the French Revolution, Boston Tea Party, and many many more. None of them were trying to conserve the past or use legal means to gain their freedom, because that fails. People in power don't give up their power from being asked nicely.
The history of liberation and the fight for freedom for all people is what I take inspiration from, going back hundreds of years and all around the world.
Every character faces social injustice, among many other types of injustice, such as political and economic injustice. I wrote MC in a way where he cares about the world through his favorite people because caring about the world first and people second is unfortunately not really how humans work. We're more selfish. Most want to live for their loved ones, you know?
No, they do not want to be "safe", they want to be "free". They are putting themselves in grave danger for freedom.
Harem Hotel is free and always will be if I can keep it that way. I think all books should be. There are an infinite amount of copies of HH in the digital era. Donations put food on my table, clothes on my back, and well much more. I'm very lucky to not simply survive, but thrive with my work.
90% of each character's story focuses on personal relationships between characters where politics and ideology are in the background. It's all about the characters, first and foremost. If it was not about the characters, I would just cut out the slice of life, character growth, relationship development, drama, sex, outfits, etc etc and cut straight to random people you don't know whipping out the guillotines. But what fun is that? A reader needs to be invested to continue reading, and HH isn't a history lesson or a documentary. Within a story, you cannot jump to the boss fight and retain the same emotional impact and catharsis you would have if you connected to the main characters and want to see them thrive, and the enemy vanquished.
Since most people are probably aware of One Piece, and our stories share similar themes, try considering what that story is about and what it focuses on. The characters are the focus, each one of them has a different political theme (being a slave, being from royalty, being dirt poor, oppressed by the world government, etc) and each one of them has a dream they want to achieve that is prevented by outside forces, and each battle is a battle of ideology in the background. But we fall in love with the characters and their growth first and foremost. How they connect, how they disagree and fight each other, how they grow, how they love. This is a very similar formula to HH.
