You don't have to. One of the biggest misunderstandings about canon is that it's some kind of rule that's binding on fans. It's actually just a descriptive label to differentiate the core material from its tie-ins, but fandom insists on ascribing all sorts of mythical importance to it and worrying more about it than they have any reason to.
Fans don't have to care about canon because they aren't employed by the film or TV studio and don't have to follow its instructions. The
makers of the shows or films don't have to care about canon because what they create is
automatically the canon by definition, even when it changes older canon. The only people who actually do have to care about canon are people like me -- professional tie-in authors working under license from the studio and contractually obligated to avoid contradicting the canon.
Of course it can be useful to think about canon as a category label, as a way of differentiating the core work from derivative works in a critical discussion. But that's just classification, like differentiating insects from arachnids or Old World monkeys from New World monkeys, say. It's not a matter of value judgment or "truth," since it's all just made-up stories anyway. And it's not something anyone
needs to worry about, just something to consider if one is curious. So there's no need for it to be a matter of controversy or drama.
