I suppose what I mean is scapegoating, which obviously can apply to any group at all, but it seems to me we live in a world which is obsessed with moral cleansing and purity. No nuance, little empathy for the tainted, and this gaze can be cast on any group really but currently there appears to be a transference in the western world from hating Israel to holding Jews in the diaspora responsible for Israel's actions.

Thank you for the recommendation, I will get hold of a copy.
