I'm pretty sure that the Campaign Against Antisemitism are not exactly an unbiased and authoritative source on what does or doesn't constitute antisemitism, given that their entire purpose is to campaign against antisemitism.
I don't quite understand your post but I'm fairly sure that the Campaign Against Antisemitism doesn't speak for all Jewish people (potential targets of antisemitism).
I don't disagree that what Myers said is antisemitic, I'm just saying think about who you consider an authoritative source.
