So even the Jews in the Labour Party are liars who are prepared to appease Antisemitism by covering it up

The bloody woman removed her blog as soon as it was brought to notice - if it was a "mistranslation", why not leave it up to prove that fact.

It was not even her words.
She posted it in the immediate aftermath of a terrorist atrocity that had brought shock and outrage to the whole country.
Three schoolkids were kidnapped on their way home and butchered by Hamas.
The post called for those who aid the terrorists to be treated as terrorists themselves. She withdrew it when her outrage subsided.
