RetardEra 

Also known as ResetEra. Its a shithole of a “gaming” forum where mentally retarded libfaggots like trannies and bulldykes autistically screech and moan about games, companies and devs that don’t suck off their Cultural Marxist agenda like adding trannies, faggots and wahmen for the sake of muh diversity. And when they’re not demanding that game devs should pander to them (even though they are retarded filthy casuals who don’t play games), then they are pathetically sperging out that some company or some dev hurt their poor shitty feefees. Its a basically if Tumblr was a forum.

RetardEra infester: This game needs to be muh inclusive and diverse so the main character must be a rainbow-haired lardassed nose-pierced trannyfaggot that has nothing to with the game or else I’m going to chimpout and try to doxx the devs waaaaaaah.
Anyone with a brain: Please go do the world a favor and end your worthless life by slitting your cum infested throat, you fucking worthless mongoloid.
