The thing is its not drawn as a culture, traditionally speaking .. Its drawn as a perversion for the fans...it really is the disgusting aspect of onepiece
You can't compare tragic themes like slavery that have substance and add narrative depth to the story to fan service.. Thats quite the false equivalency there.. Especially with Bonney being a minor when for the last decade she was an adult and making kids like Momo perverts
I'm not saying that 16th century was a paradise on earth for humans but to allude that eye candying 10 year olds is decent and a moral representation of what Oda thinks his story should be is wild especially for a shonen manga in a day and age where porn is rife and women are mass sexualised.
Oda isn't beyond criticism mate
Didn't say Oda isn't beyond Criticism, i have no respect for him even if the Manga was 100% Clean & Perfect
But who decided that Slavery is good for Narrative Depth & Story? Who decided that Zoro saying "I don't believe in God" is good for every Reader who is Religious? Who decided that anything in One Piece needs to exist? Who decided that Luffy is the Main Character?
There is no such thing as this is Good for Story & this is not
One Piece is just a Single Human's Thoughts put into Drawings & Words, nothing more, nothing less
The only thing that differentiates it from just having a Conversation with him is that it's beautified for your Eyes & Ears & Emotions
But at the end of the day, it's just Oda spreading his Ideas, regardless of the way They reached their destination & to who
Same thing for every Piece of Fiction
If such Work contains Honest Beliefs/Ideas/Morals of it's Maker, then it will definitely include their Evil Side cuz everyone got one
Or They can instead choose not to put their Filthy Ideas in their Work to please their Audience, but again, People are different, We have different Beliefs, Cultures, Traditions, Experiences, Languages, Relationships ... etc so you will only be attracting certain People
If you wanna talk about Morality in a Fictional Work, then don't Specify, don't say "This is Good Addition to Story & this is not", cuz regardless if his Intentions are just to draw what He likes or to draw what Audience like, Evil is Evil
Sexualizing women or kids isn't the only thing that can influence Readers badly, any Evil Act can influence them badly, They can be motivated to Steal, to Rebel, to break the Law, to turn against their Parents, to follow false beliefs, to hurt people, to rape, to enslave ... etc
You think making a Villain Likeable isn't same as Sexualizing the Heroine?
You think making People fall in love with Doflamingo or Crocodile or Gorosei or Aizen or Madara or "Insert Any Villain" here is Good for Story & not same as making them turned on by Fictional Girls? It's extremely bad as well, if not worse
One Piece is still Trash even if it never included any Sexual Scene of any type
You can read it as "Guilty Pleasure" where you take what u like only & ignore what's bad for you or u don't like
But as an Influence? It's obviously Garbage & same for 99% of Fictional Shit
Oda is a man with No Values, He is among Worst Famous People of this Era
His Story is just one big promotion for Chaos
