A thing I've noticed that fans seem to get off slightly is Jim Gordon. Specifically his intro/connection to Bruce though I understand the likely causes.
In adaptations, specifically live action like the movies and TV Show Gotham which are generally more accessible than long complicated at times comic runs for most people, Jim Gordon is connected to Bruce and that he was their the night the Waynes were murdered/in Bruce's youth which is not a traditional element of his story.
When in the very famous comic story that shows his past and arrival, he is tied to Bruce by both arriving to Gotham at the same time (or in Bruce's case returning). Jim moved there in Year One and became invested in Gotham. He and Bruce met as adults.
And, yes, making him there in those specific worlds works but if your are being comic Canon or mostly comic Canon OR discussing events in the comics especially during certain timelines it throws me. And maybe they changed this in New 52 or Rebirth. I haven't read enough to say but this is usually connected to major events that are distinctly not N52 or Rebirth.
It's a smaller thing since the Gordons aren't often the main characters but it is part of a trend of things that pile up. Like Steph being from Crime Alley too (she's a suburbs girl!), Tim's parents being alive well into his Robinhood, an incorrect Teen Titans lineup for Dick, getting the story of Jason's return wrong, etc. (all the Batfamily suffer from this), all take me out for a minute.
And I am not judging people for not knowing everything or repeating what they see over and over in other fanfics. That can be a common way of learning lore events while working through source media. And I've been guilty of assuming events/info a lot of people are repeating a certain way is accurate (see Jay&Tim meeting in Titans Tower).
This isn't even really a complaint?
It's just...if you are going to make meta or argue about a certain character's position or talk about/analyze them or try and make a joke, can you at least be accurate? Especially if you allegedly care about them or are annoyed with the Character. Because it sounds like you like/dislike someone you made up, despite being very passionate that this is accurate to the Character.
