Hiyori straight up said the Kurozumi are born to be burn which contradicts everything what the entire plot has portrayed so far about descendants not necessarily inheriting the evil traits of their ancestors and thus not discriminating those based on their ancestors. This is actually such a bad message. Forget powerscaling, forget "Who joins the crew" - Oda failed at that point which people usually expect him to exceed when it comes to other stuff. Plot related topics are meant to be highlights in One Piece. Yet Oda wrote such a message. It just shows again that Kanjuro's and Orochi's hatred towards the Kozuki clan was rather justified.
