I feel like Shaun king posts get retweeted and shared because they're easier to find / more detailed, especially early on. The reason why I heard about this was because someone I follow (who also doesn't follow Shaun king) shared a shaun king post on their story.
So I try to separate people that re-share his stuff, from the guy himself
I'll be honest though, I don't know much of the controversy around Shaun King. I have heard people referencing issues like this but I didn't follow up properly
This controversy has been a bit unique in that people are being canceled in both directions. In a way it's actually a good thing, since it shows that debate and democracy are at least alive. You could say we shouldn't cancel people at all, but then I don't really want the guy with a swastika face tattoo being in charge of anything important. Maybe there needs to be some kind of canceling rules, haha?
FYI, the blog post starts with accusations of "equating Zionism with the genocide of Palestinians" and "using the 'from the river to the sea' chant", which are not universally agreed to be antisemitic at all, even if you don't agree with them.
