I was referring to Chuck Wendig's tweet itself.
Now it happens that I agree with Chuck Wendig on this: US democracy is threatened and being dismantled, just as it is in Poland or Hungary. I also note that Lucasfilm had earlier approved of the way he had acted online, per his own account, and that he had suffered from online harassment campaigns for daring to include LGBT people in his Star Wars novels. Not as bad as Kelly Marie Tran and other people, but bad enough. That undoubtedly informed his temper here, but he didn't threaten anyone, didn't bully anyone, didn't call out for anyone to be killed, didn't kick at anyone vulnerable.
What THIS you refer to, I have no idea myself.
