Just like WCI, everybody, the whole Fanbase, yes even/especially Sanji fans, criticized and shitted on Sanji. They actually shitted and hated on their fav Sanji. Then Wano started, and just like cinderella at midnight, it all changed, and everyone blamed it on Zoro fans.
I remember some Zoro fans even tried to defend Sanji in WCI, crazy as hell.
And check this, everytime Zoro fans want something for Zoro, it always comes from a place of good intention. When we wanted Zoro to get CoC, it was not spite Luffy fans, we only felt, based on what the story has shown, it makes sense. Same thing with Zoro going to the roof or fighting Kaido.
But Sanji fans, they wanted King not Queen, why? to spite Zoro fans. They want Sanji to have CoC, not because they honestly feel the character deserves or needs it, but to spite Zoro fans.
The OP fanbase, will never go to bat for Zoro, he is the only SH, the fanbase would never support or back up, and they will always make his fans to be the villains. So, it's good that Zoro fans are so tight knit and good at supporting each other in shining light on Zoro, because who the fuck else will.
