I think there's a difference between "cancelling" and "calling out." What we usually see is Call-Out Culture. Call-Out Culture thrives on negative engagement, they get lots of money when they make a Call-Out video, and they make up BS all the time in order to keep the wheel of rage moving, and that is quite bad. It's very different from Cancelling which was done to protect the black community originally. Call-Out Culture is often...with the intention of getting views on your call-out videos, lets be real. They don't care if it's exaggerated, and they don't care if they make a mob. They want the views.
Like the other day I saw this fashion influencer chick who liked a image of a trump rally by accident on instagram. People saw that and were really upset--thing is, the person who liked the image is an openly lesbian liberal. It could not more clearly be an accident because you know when you're scrolling on your phone and you see an image, you might tap it as you continue to scroll. Yet, people were so outraged, that she decided to make a 30 minute long teary eyed apology video to the entire black community (who, in the comments were like wtf are you talking about woman), burnt the bridge between her and her long time friends who were trying to get her to shut up, and if anyone said "this is insane" they were told they were being racist and had to shut up. The situation exploded in everyone's face who tried to even approach it.
Stuff like that is clearly call-out culture, which is very different, and the way to address it is to not address it. The internet can make it seem like ridiculous statements are legitimate, since all are delivered on the same platform. If you give it credence, even to say "this isn't true" then you've acknowledged that this has been a problem and you've given them ammunition to start their attack. Like there comes a point where your fans and readers need to use their damn brains and see what is probably not real.
But as far as being cancelled because you did something hella racist, that's why prevention is the best policy. Do your research so you can cite your research basically. There may be people that are mad because you may be writing something that isn't exactly about your race or identity and you have to let them talk about it. You don't have to read their articles, you don't have to acknowledge them, but yes, you have to let them discuss it.
Like the whole thing that went down with Critical Role--the person who was criticizing them was writing an opinion piece. They had no real solution to what Critical Role could do differently, they just wanted to share an opinion that they knew would get a lot of views, and it was a spicy opinion they may have deep feelings about. It was such a hot take that Critical Role doesn't even have to address it. They were not really "cancelled" so much as Called Out, and I don't think that the even author of the article against Critical Role deserved the amount of backlash they got because it's just an opinion piece on Kotaku. Sometimes you have to let your fans decide for themselves what they want to think.
