I’ll cut to the chase: David Baddiel’s book about anti-semitism and how it’s often treated as a second-class form of racism is very much a worthwhile read. I’m sure you can find more academic works, or with more detail, but even in this short text, he’s able to passionately and effectively makes his case.
I had a sneaking suspicion that I didn’t fully understand the subject, and it does a nice job of filling in those gaps. As he notes at one point, there are lots of oh yeah, I suppose so, never really thought about it like that moments.
