Soooooo much fandom discourse is centered around the fandom not the media itself. But opinions tend to be foisted upon the media itself. A bad shipwar can damage a show's reputation, even if the show has not encouraged it. Memes or adaptations or initial reactions can create warped versions of the characters. Except these warped versions then impact how the actual character is perceived. Bad media literacy can lead to people claiming a work supports the actions of someone vile, even if the work opposes it. Certain fan theories or art designs can gain a life of their own, only for fans to be let down by the actual result, even though no promises were made. Fan favorite characters can create feelings of anger that something 'wasn't addressed' even if it was superfluous. An popular show can create resentment and toxic behavior surrounding itself, even if the show itself is great. Creators get dragged into the fray, and because they are actually creating and not spending time learning the intricacies of the fandom they inevitably offend someone.
In conclusion Fandom Toxicity is going to be present no matter how perfect the work of fiction is. Because it is nearly always the fans causing problems and projecting it, not the art itself.
