In the nature of the last thing about fictionkin I reblogged, let me go on about of a shpeal.
Being fictionkin does not give you the right to someone else’s characters, whether they’re published or not; it does not give you the right to dictate how other fans draw, write, cosplay, RP, etc that character. And it especially does NOT mean you know a character more than the creator because “you are them”, that is so rude and disrespectful.
I don’t care if you identify as fictionkin, you do you. But claiming entitlement to a character that isn’t yours isn’t cool. It’s not cool to say actual goddamn canon is wrong, because it doesn’t fit your “canon”. It’s not okay to say that the author was wrong about their own story.
It’s not okay to harass other fans either, because you don’t like how they’re enjoying a character that you have no ownership over. You know who does? The author. Stop telling people what to do and harassing them just because of your kin ID. Oh, and respect artists, don’t tag their shit as kin if it bothers them.
