Here is the conclusion to an incisive article by former Chief Rabbi of the British Commonwealth Jonathan Sacks.
"Anti-Semitism has always been, historically, the inability to make space for differences among people, which is the essential foundation of a free society. That is why the politics of hate now assaults Christians, Bahai, Yazidis and many others, including Muslims on the wrong side of the Sunni/Shia divide, as well as Jews. To fight it, we must stand together, people of all faiths and of none. The future of freedom is at stake, and it will be the defining battle of the 21st century."
