It's pathetic how Yasuke has basically become accepted as a real person who definitely existed. The propaganda has been put on repeat and pushed for so long now that any debate of his actual existence is over.
Talk to any retard and they will not even entertain the idea that the "evidence" from Jesuit writings may have been fabricated or embellished for the sake of a promotion. They will merely say that there is other evidence, without knowing what that evidence is. The idea of even questioning his existence is seen as taboo to the average normie. Even people who are against his inclusion in Assassin's Creed are merely arguing that he was only a "Retainer" and not a "Samurai," giving legitimacy to the historical revisionism that is being attempted.
The overton window will continue to shift to the point where Yasuke's existence will be elevated to "he was an important warrior in Nobunuga's army" because leftists and dishonest Historians will pull shit out of their ass and reference each other in circular reporting until the normies begin to accept it as true because it makes them sound smarter to know some random historical fact.
The guy who wrote the original story for this game came out and said that they changed it to this. I would think it would be a slam dunk. Im aware Yasuke existed and even if he was a samurai (mostly what I see is he was a bodyguard or squire) I still think it makes more sense to play as a Japanese character in a game set in that time period in Japan
