I'm actually having a hard time deciding between several solid contenders (and their totally-not-their-alts alts) but I'll go with one that I had very little actual interaction with: the "cranking the hog in front of coworkers whether they want to see that or not is liberating and if you're against it you're a reactionary scold" Whedonbrain we had that one time. :volcel-judge:
I missed a lot of it, but there was a wrecker who got really upset about pumpkin spice so he got banned, then he kept making alts with Hanna-Babera themed names.
What the fuck could a person possibly have against spices? Were they British?
