I love how you make it impossible for people to have a discussion with you, you act like a victim instead of a grown up. You're "blocking me" because I treat you like how you treat me and others, by laugh reacting. I only did that because you acted immature first.
Importance ≠ canoncity. Gunn thinks these are all non-canon because they're all equally unimportant to him. Neither the novel or comic are required to understand Superman, therefore they're "non-canon" to Gunn. This also applies to the Krypto shorts. Your personal opinion on whether they're important or not doesn't matter because my mom could watch Superman and not be confused or lost, so it's not really that important.
It's not a false dichotamy because that implies there needs to be a more nuanced view, but there doesn't.
1. Both set themselves in the DCU.
2. Both have been called non-canon by Gunn.
There, simple.
