My estimate, based on several analysis, is that the Fediverse is about 3% explicitly antisemitic. This is based on analysis I've done on hate messages across the Fediverse, analysis on my own posts, etc.
Then there's another layer of people who believe antisemitic lies and will spout the, though often they'll do it "carefully" so as not to show the appearance of hate. I have many examples of this. These kinds of people are peddlers of social capital and see that they can get away with advocating violence against Jews in coded language in one post, then be celebrated by saying they "Don't hate anyone" in another- giving cover to their hate.
Finally, there's a huge majority that is simply silent. They don't want to "get involved".
Well as John Mellencamp says "Silence is Complicity".
