Fillers (anime) aren't canon because Kishi has nothing to do with them. It is not his story, and some elements can be a little exaggerated. So like I and @Elveo said, depending on fillers to justify your arguments really isn't the right way to go. I'd go with what Kishi writes in the manga, rather than another rendition of his story.
