Getting more honest than this hater anon probably deserves: It's such a sad thought that someone might genuinely think shipping is impossible if it's not canon. Such a lack of imagination and fascination with the material.
Even if it's non-shipping, isn't it just interesting to think about your favorite characters, the world they live in, their relationships, the potential to see them in other non-canon settings?
Does anon also never daydream? That's so sad...
