The UK Labour Party are being criticised to not accepting the “International Holocaust Remembrance Alliance’s definition of antisemitism” in its entirety.
I’ve listed the complete definition at the bottom.
One of the problems I see with this is that we could subsequentily be inundated with similar “anti” this and that documents from all and sundry. For example, AntiMexicanism” ( Trump would fall foul of such a definition, I’m sure). AntiIslamism. Well, in such a definition I’m sure that all negative references to the faith and its founder would be seen as dangerously AntiIslamist.
AntiPalastinist would include all sorts of definition that,surely, Israel, and Jewish people generally, would never sign up to.
   I’ll just want to comment on one “definition” from the complete list below.

“Accusing Jewish citizens of being more loyal to Israel, or to the alleged priorities of Jews worldwide, than to the interests of their own nations”.

This is a very dodgy one. Surely, there must be some UK/USA Jewish citizens out there who, when push comes to shove, would put Israel before, say, the USA or the UK.
Just as there were British citizens of Irish decent who would have put certain Irish causes before the UK’s position. And, of course, there will UK/USA etc Muslims who would put Muslim causes ahead of their adopted country’s position.

There are lots of examples of citizens of, say, the USA who would put their religious beliefs ahead of their country’s needs. Take Quakers, for example, when they say that they would not fight for their country, surely they are saying that in their country’s hour of need they would not answer the call because of religious reasons.

Now, follows the complete “International Holocaust Remembrance Alliance’s definition of antisemitism”

Calling for, aiding, or justifying the killing or harming of Jews in the name of a radical ideology or an extremist view of religion.

Making mendacious, dehumanising, demonising, or stereotypical allegations about Jews as such or the power of Jews as collective — such as, especially but not exclusively, the myth about a world Jewish conspiracy or of Jews controlling the media, economy, government or other societal institutions.

Accusing Jews as a people of being responsible for real or imagined wrongdoing committed by a single Jewish person or group, or even for acts committed by non-Jews.

Denying the fact, scope, mechanisms (e.g. gas chambers) or intentionality of the genocide of the Jewish people at the hands of National Socialist Germany and its supporters and accomplices during World War II (the Holocaust).

Accusing the Jews as a people, or Israel as a state, of inventing or exaggerating the Holocaust.

Accusing Jewish citizens of being more loyal to Israel, or to the alleged priorities of Jews worldwide, than to the interests of their own nations.

Denying the Jewish people their right to self-determination, e.g., by claiming that the existence of a State of Israel is a racist endeavor.

Applying double standards by requiring of it a behavior not expected or demanded of any other democratic nation.

Using the symbols and images associated with classic antisemitism (e.g., claims of Jews killing Jesus or blood libel) to characterise Israel or Israelis.

Drawing comparisons of contemporary Israeli policy to that of the Nazis.

Holding Jews collectively responsible for actions of the state of Israel.
