TW: racism, antisemetism, transphobia.
When I was six, I pretended to be racist because I was obssesed with being evil and wanted to pretend to be the "bad guys" we were learning about in school(i.e. mimiking things the "bad guys" in history were saying with no reason as to what the consequences would be and thinking it was fun). (I was also misoandrist until the 8th grade, but that's a different story). I don't know what I was thinking and I didn't think to consider how other people would feel about me or how that would affect me. Fortunately, the adults around me were responsible and I took the time to educate myself and people forgave me once they found out I did so. That incident still haunts me to this day, especially since I learned how terrible racism actually is. Then when I was 14, I was in this internet forum that told antisemetic lies that I believed (i.e. Jewish people are bad writers) and kinda ended up saying those awful things to some of my Jewish classmates, and also said something I didn't know was antisemetic. Fortunatly, the adults around me were responsible and made sure I was educated, and I also made the effort to do so. When I was 16, I became jealous of my trans brother because I felt he was getting more attention and support from my dad ever since my mom died. This caused me to be hostile toward trans people including supporting transphobic creators and telling transbhobic jokes. It was only when my childhood best friend came out as trans that I realized having a community and sticking up for others and making them happy made me happier than trying to hurt my brother and other people. Only when the person that I hurt when I was 14 gave a speech about antisemetism in school assembly did I realize how much I traumatized him, along with all the other people I was prejudiced against. And it makes me feel bad every day. But I have learned a lot from these experiences, and while I fear traumatizing people and driving them away because I do or say something wrong, I know how valuable learning from my mistakes is.
When the past racist streams and videos with Micheal Kovach and Ashley Nichols and Brandon Rogers were dug up, I was dissappointed by what they did, but relieved they were able to learn and grow from their mistakes. But when the fandom starting harassing them for the actions that they CLEARLY regretted and have learned from as if they were STILL racist, it made me hurt like hell. I worry that they will become more extreme and start harassing more people when they have been revealed to do something bad in their past, even when they have learned from what they did. I'm worried that this unforgivingness extend to entire GROUPS of people. I'm German and one of my constant fears is people not forgiving me when they hear of mine of Germany's past actions and being isolated by people I thought I could trust, even though I am no longer prejudiced. I also fear for my childhood best friend, who is half British-Jewish and has learned to be less misogynist, and for my new twin friends in college who share my childhood friend's heritage and have no intention of hurting women. I fear for all other groups of people whose reputations are tainted by the atrocities they committed. If Hazbin Hotel's message is that redemption is possible, people NEED to take this message to heart, otherwise, people hoping for a safe space where they an hope to better themselves will have broken promises.
