Let us suppose, for sake of argument, that Ice's "supersessionism = anti-Semitism" logic is valid. Ice feels that since Jews have been persecuted by some Christians, we should look for a sufficient cause for that persecution. Ice finds a causal factor in the doctrine of supersession. But let us consider an even "better" argument for anti-Semitism and intolerance of Jews that provides us with an even more obvious smoking gun, employing Ice's "logic."

Ice's logic goes something like this: (1) Anti-Semitism is evil bigotry that must have some explanatory cause behind it. (2) Some Christians hold that God no longer maintains a special place in His plan for the Jews. (3) These Christians have a sufficient cause for anti-Semitic persecution of the Jews.
