Galaxy? I thought I was Gaimon? Well, at least you're sticking with the G theme.

If I may paraphrase just a bit: canon is not just as simple as "what is shown in the manga".

Everybody believed Beta Beta no Mi was a logia since it wasn't hurt by Plantanus Shuriken. It was obvious Sabo was alive from the beginning since he was never shown dead on panel. (It cut away, remember?)

Sabo being alive was canon from the start. Besides you're using a stupid definition of canon. Beta Beta no Mi being "logia" wasn't "canon" since he was later revealed to be paramecia.

And please do post the definition of canon if it'll put an end to this nonsense. Because making guesses based on what you see in the manga is the textbook definition of speculation. The difference between canon and speculation is not whether or not the guess is right; it's actually having confirmation of the facts.

Something can seem to be canon if it's really obvious to the readers (ie. based on Luffy's build and personality, not to mention the fact that he's the main character in a shonen manga, he's definitely a teenager), but it's still just speculation until it's confirmed (ie. the SBS that gave Luffy's age).

FraRo, Sabo dead and Beta paramecia are all guesses you've made based on what you saw. However reasonable it may be to make those guesses, until they're confirmed, they can still be proven wrong, as in the case of Sabo.

To put it simply: canon is what actually happened in the manga, not what you think happened in the manga.
