Pretty self-explanatory title. For me, I have two ruined fandoms, one I recently joined again. Undertale and Harry Potter. For Undertale, it was all the incest and selfcest, which I was reminded of when I tried to look up swap sans and was met with 'swap sans x fell sans'. And for Harry Potter, it was all the GODDAMN POTTER PUPPET PALS JOKES BECAUSE OF MY PFP!!!!!
