The world of One Piece is crazy. Momonosuke can now transform into a pink dragon that can levitate castles. Who cares if a person is "transindividual".
I'm more surprised nobody suspected Yamato for being Kaido's child. I guess Yamato just tells them Kaido broke all of his bones since he was a child, and they are like "That's 100% something Kaido would do".
Doesn’t even have anything to do with the trans discussion at that point. There are time when people go so far in thinking they’re doing the right thing that they end up disrespecting someone else, something Yamato will have to deal with in this brand new world she’s beginning to explore.
I think can end up very much being one of those cases for Yamato, who’s not particularly mature due to throwing temper tantrums against Kaido all her life and not getting to socialize with casual people most of her life too.
Also, I get the feeling Yamato hasn’t really even interacted with most of the Wano citizens. Her time outside of Onigashima was in the capital, and even that much of that so far was spent on roofs waiting for Luffy and Zoro, as well as having fun with the Straw Hats thereafter, with the citizens prob being too busy to pay much mind to get either.
But now that the celebrations have been had and Yamato will now explore Wano for the first time, she’ll def be meeting various citizens throughout the towns, which leads me to believe Yamato may end up casually mentioning she’s Kaido’s child in front of them and holding a grudge against her because she’s blood-related to that tyrant.
If all the citizens end up putting aside any prejudice towards Yamato due to her part in the raid, then I’ll gladly admit I was wrong, but considering cases like people being ready to hate on Ace for being Roger’s child, I think I’m within reason to have that speculation in the meantime.
