Before this site kicked the bucket, I actually wanted to make a thread about these guys because I found the whole thing hilarious. In case you don't know, there once was a forum called NeoGAF. It was full of people who hated japanese games because they contain child porn and generally complained whenever there was a woman in the game who showed some skin / there was a woman in the game who didn't show skin.
They also had a total meltdown when Trump won the election. Yeah, a video game forum was having a meltdown over Trump being president. Anyway, a bit after that, one of the higher ups got accused of sexual harassment. He ran off pretty quickly and left the place in disarray. When the forum got sorted out, the new administration decided to employ more common sense and rediscover what it meant to be a forum about video games - as in focus on video games and video game discussion and not outright ban people for disagreeing. A lot of the members didn't like that and thus resetera was born.
That place is pretty much the old NeoGAF 2.0 - echo chamber, witch hunts, feelings etc.
The latest big thing was when subnautica was released and it turned out that a sound artist for the game made some tweets that clashed with the ultra liberal views of resetera and this a topic was created.
Check this shit out, it's hilarious https://www.resetera.com/threads/subnauticas-sound-designer-is-apparently-racist-and-transphobic-update-fired.21140/
Also, thread whining is when you disagree with the topic and basically tell people to chill out.
