For months now, week by week, examples have been emerging of cut and dried anti-Semitism – most dressed up, oh so cleverly, as anti-Zionism, but much not even bothering to hide it. And the Labour leader's response to the criticism that he is soft on anti-Semitism and that it's his political mindset that has fuelled its rise is not to get hard on anti-Semitism. It's to get irritated.

This is not some academic exercise or interesting political theory. This is reality – the reality that the Labour Party is now run by a cadre for whom anti-Semitism really is ok, so long as it is dressed up as anti-Zionism. Because Zionism is the enemy of all good people.
