There is nothing uncivil about this comment:

The worst antisemites in the world are Israel's criminal regime and its supporters.

Their program of cruelty and madness denigrates Judaism, strips Israel of its legitmacy in international law, and unnecessarily costs lives among innocent Israelis.

The zionist antisemites come in two varieties:

-There are nutbar Jewish zealots whose religious mania convinces them they have some twisted right to steal the land of another people.

-There are wingnut Xtian nutbars whose religion tells them the conflagration of destruction and hate they deeply desire will come to pass when Israel has stolen the land of another people.

It's creepy seeing these two natural enemies cozy up to screw up the whole world, and amazing how they can ignore the elephant in their room.
 
Both those gangs are only too happy to sacrifice all of Jewry on the altar of a mad ideology of either zionist determinism or Xtian armageddon, and that makes them antisemites.
