Kevin,
The piece about the Israeli minister of justice very clearly showed her seeking to identify significant criticism of Israel as essentially antisemitic.

It really did not.
She said that antisemites used to be able tp speak against Jews, but now they speak against Israel.
It is obvious that antisemites will speak nagainst Israel, but it is a logical fallacy to interpret that as meaning all who speak against Israel are antisemites. None of us here have claimed that, no Israeli minister has claimed that, and it is not an issue in the Labour Party.

Antisemitism is something quite different from criticism of the actions of the state of Israel,

Of course it is. No-one is disagreeing with that so why say it?
Nevertheless, some critics are indeed motivated by antisemitism. Does anyone deny that?
