Your first sentence contains two contradictory statements, and KF actually had a whole GamerGate subforum at one point. At this point I think a subforum would be nice just so those who like to post every… single… thing their favorite cows tweet could have their own threads to do so in.
Anyway, a thought: Those commenting on the novelty on this particular culture war battle involving the law are forgetting ComicsGate and the resulting and ongoing Meyer v Waid lawsuit.
It has its own thread, but here's a quick rundown.
Richard C. Meyer is a retired vet who reviews comic books on his YouTube channel. Despite non-existent production value in his videos, his channel took off like a rocket in 2017. In his videos, he usually criticizes what he sees as a social justice takeover of comics and rags about things like black characters which aren't allowed to have flaws or 110-pound women with danger hair who are able to knock out muscle-bound men with one punch. His older videos could be quite caustic; he's mellowed out a lot over the last year or so. He ended up making a lot of enemies in the comics mainstream and was eventually doxed (he originally tried to stay anonymous).
He had done a few of his own books before, and last year he announced that a sequel to one of his previous books, Jawbreakers, would be published by a publishing company called Antarctic Press. But not long after the announcement, Antarctic backed out of the deal. It looks an awful lot like this happened after a long-time comics professional named Mark Waid called Antarctic and threw his weight around to get Antarctic to not work with that alt-right bigot misogynist Meyer, so Meyer lawyered up and is now suing Waid for tortious interference. Nick Rekieta started covering this case, which led him to looking into the Mignogna stuff after much of the ComicsGate community started to notice it. Nick reached out to Vic for an on-stream interview which ended up not happening, but apparently he did bring up the idea to Vic of consulting a certain law firm in Texas about a possible TI case, and the rest is history.
So, yes, this particular lawsuit-in-the-making is great and will hopefully help stem the tide of callout culture, but it's not the first! Without Meyer v Waid, there'd be no Mignogna v Whoever.
