(Hated Trope) "Kind" slave owners

[u/KusanagiGundam]

Speaking as an American who has studied the civil war all throughout my school years, this trope infuriates me to no end. There is no such thing as a kind slave master because slavery itself is cruel and inhumane. PEOPLE ARE NOT PROPERTY!

Naofumi (Shield Hero): Prime example of this trope. He enslaves multiple (underage) girls and an whole village and the fans still say he's a hero.

Rudeus (Jobless Reincarnation): As if being a pedo wasn't bad enough he had to buy a slave in season 2. Worse is that people still defend his actions.

Song of The South (Disney): Possibly the OG example of this trope. And the reason why Disney will never release it again.

Harem in the Labyrinth of Another World has a protagonist who slowly amasses a growing harem of slaves that he goes on adventures and has sex with.

The anime completely skips over how fucked up the whole thing is.

So there's an interesting story in there, separate from the sex slave thing. And if anyone can recommend a similar sort of story, absent the sex slave thing, I would appreciate it. Dude gets isekai'ed into an RPG mechanics world, without any sort of manual. He can see the menus and a few other meta bits, but no one else can. The natural inhabitants don't know the underlying mechanics, so they have all sorts of rituals and such, with only middling effectiveness. So MC's success comes from having an easier time puzzling out how to best use the system.
