The thing is, if you identify with and project onto a fictional character, no one on here is gonna judge you. No one! We all do it.
But the second you start treating people poorly because they like/ship/talk about/write a character that canonically or otherwise isn’t nice to your blorbo, you deserve to be called out and told to stop.
“Bruce Wayne is an abusive Father to [Batkid] and I don’t like reading about him” = fine, we all have preferences!
“Bruce Wayne is an abusive Father to [Batkid] so I’m going to send shitty messages to Bruce Wayne-related blogs and make fun of the people who read WFA” = what the actual fuck
Some of us self-insert a little too hard and really need to dial it back. Yes, Tim/Damian/whoever is your person, your beloved blorbo, you with a few extra steps, but that actually does not give you permission to be an asshole to other human beings.
Yes, even if said character was wronged/hurt/messed up via canon. You are mad at a FICTIONAL CHARACTER, not me!
