Nobody is like that. Pretty much every canon obsessed fan has at least one piece of canon they want to get rid of.
Many fans of canon will also have "I love this incensed parody comic but I'm glad its not supposed to be in continuity because characters acting out of character is funny as a joke but not as a mistake".
All stories are just made up Carp. The canon is part of the story. People don't generally read part 2 of a trilogy and then say "I don't care if the author says part 1 and 3 are canon, that's just some Salmon he made up to sell me 2 more books". Sure the odd person will say "book 3 was a disappointment and this Turbot is how I would prefer to think it ended" but they don't consider the whole idea of stories being set in a coherent universe to be a load of old dogfish.
