and it is not difficult to discern.

Not all Jews are Zionists. Not all Zionists are Jews. Not all Jews are Israeli.

Almost 90% of Italy's citizens are Catholics, but you won't see these bigots referring to Italians as "Catholics." And I haven't seen them questioning the loyalty of American Catholics. The posters at that Forum make accusations that American Jews are loyal to Israel. Two have gone so far as to call American Jews, traitors.

This is not anti-Zionism and no one could confuse this sort of hate speech for political arguments against Zionism or Israel. This is Jew-hating. There is a difference, and there is nothing mysterious or arcane about it.
