There is a clear line between criticism of Israel and anti-Semitism. If someone chants ‘Free Palestine’ on a protest that is not in and of itself anti-Semitic. Nor is holding a placard bearing the same message. Having debates about the Israel-Palestine conflict, whichever side different individuals take, is not racist, either.

But daubing ‘Free Palestine’ in an area of London with a large Jewish community is undoubtedly anti-Semitic. Attacking a Jewish school boy in London in an attempt to force him to chant ‘Free Palestine’ is anti-Semitic. Screaming ‘fucking Jews’ at Londoners putting up posters about Israeli hostages in Gaza is clearly anti-Semitic. And, for the avoidance of doubt, entering a Jewish supermarket wielding a knife and demanding to discuss Israel and Palestine is most definitely anti-Semitic.

Anyone who refuses to recognise that anti-Semitism now poses a serious problem has, at best, lost their moral compass. At worst, they themselves might be part of the problem.
