Aaaand abusers gonna abuse. I definitely want to be informed if I’m being an ass and don’t realize it, but if the person saying it is making up things about me, twisting my words and acting in bad faith, I’ll assume they’re just trying to hurt me.
Also: I’ve had this username for over a decade. I’m not going to abandon a part of my identity that I care about, especially not if making me drop it is one of the goals of harassment directed at me. I’m not important, my thoughts and feelings don’t carry much weight, but I’m still me. Harassment isn’t going to change the fact that I’m alive.
