Allow me to suggest there's a third item in the mix: if all of us who grew up in this time have some unconscious racial bias in us--a bias which seems to be about four or five centuries old--how much deeper might unconscious, or semi-conscious, Judenhass might be as that dates back between eighteen and twenty centuries, maybe more?
I think we need to do some serious self-scrutiny and include Judenhass among the racial biases we need to neutralize within ourselves and our societies.
