Yeah fandoms can turn one against a character. Tim is a great example. Robin fandom is pretty toxic but Tim fans are on another level of toxicity, entitlement and pettiness.
On this very site when Duke was first introduced they created a mock Appreciation thread for Duke just to bash him. That's some creative hate and dedication.
It's just comics.
The hate against Damian continues till today and on AO3 poor Dick Grayson for his crime of making Damian Robin the majority of his SFW non TT fanfic are stories where he suffers for, get's punished, regret's, is hated by other heroes for kicking Tim out, gets yelled at by Batman when he returns for making Damian Robin and kicking Tim out, comes crawling back to Tim, made to apologise for making Damian Robin and kicking Tim out [a thing that never happened in the comics]... etc You get the general theme.
My Gosh it's comics and that was over 10 years ago.
Jeez.
Anyway don't like Tim Drake and 70% of my dislike comes from experiences with/behaviour of his fandom.
30% find him bland and his origin story is just the worst. Tim as Robin is very toxic and super damaging.
Turned a mantle for giving a young lost orphan a hopeful purpose into a teen in charge of batman's mental wellbeing and regulator of his actions.
The kid shouldn't be responsible for an adult's actions/mental health. That puts a ton of emotional stress and strain on a kid.
Bruce can't control yourself then move into a hospice.
