A lot of what goes on at ERA is performative. If they were true to their convictions, and ERA was as unsafe for "insert marginalized group here" as they constantly whine about, they would have either left for Discord, gone to some other community, or they would have raised hell until the mods either acquiesced to their demands or--far more likely--banned them. But they don't. They leave their bitching to approved whining threads, or make a post or two in other threads and only go further until after the mods approve of their shitposting. They all value their ERA accounts and access to the community too much to risk it. Which tells me they are mostly posers that just want to exert their power over the community through the mods.
Ketkat may have been insufferable, but she seemed to have been a true believer in the shit she spewed. Enough so that she ate a perm ban for it. Do you think someone like excel, Messo, or NoblesseOblige would go that far? I think not. Hell, look how quickly they forgotten and abandoned Kekat after staging a revolt to get her unbanned the first time.
