Dude. I can name so many other fandoms that are more toxic than Jojo. Even if there’s shitposts at times, it’s all in the vain of love and support for the source material (which is more than I can say for some). So please Ofer, I’m saying this as a fellow fan who has only love for Jojo. Let this all go.
In PHF, it’s revealed that Canolo Morolo (one of the main characters in the story) was the one who gave La Squadra the lead about Trish and Sardinia while in the anime, they get it through interrogating Passione’s intel team (of which, Morolo is not a part of) and it’s because of this inconsistency that PHF can’t happen.
