Could you please do us all a big favor, Horrorfan, and not directly reply to these posts if you're not going to read a single thing in them?
I already said, "assume that the Venom fight is canon." That means that I am assuming the Venom fight is canon. It does not mean "I still don't think the Venom fight is canon." If that's what I meant, I would have said it. But I didn't. So there goes the first three paragraphs of your post.
My point was that even if the Venom fight is in canon, you can't hold it up as some sort of supreme proof of Venom's superiority because someone like me would then readily reply with pictures of Superman moving moons and planet around. You know, like exactly what has happened in this thread that you've been reading? If both are in canon, then the only way you would still be able to tout Venom's superiority is by ignoring the canonical evidence that I've given you. Which, coincidentally, you've done.
So how exactly do you determine whether one piece of canon is more canonical than the other? Well, that's a big subject matter that I don't truly have the answers to, but what I do know is that you've determined that one piece of canon is more canonical than the other purely and utterly out of BIAS: you don't mind Venom beating Superman but don't like it when DC characters move planets around, so you've elevated Venom beating Superman as higher canon than him moving planets around. Which, by the by, is exactly what you continuously accuse other people of doing. Glass houses, chum. Glass houses.
If Superman can move planets and is still being beaten by Venom then that's just bad writing, period. It has nothing whatsoever to do with comic book logic, and I have no idea why you are still harping on that because it is an entirely different subject matter. Comic book logic means that certain things happen in this fictional universe which do not happen in ours, but always with its own rules and logics. It does not mean that random illogical sht happens with no explanation or reason. Venom beating Superman definitely ranks as random illogical sht happens with no explanation or reason.
