Miller claims he suffered discrimination when he was fired two years ago because his anti-Zionism counts as a philosophical belief under the Equality Act. This is no mere critique of Israeli policy. Miller believes that Israel should disappear completely. "Our cause is not to establish a Palestinian state but to dismantle Israel", is how he put it. It feels like an appropriate moment to be asking whether such a belief can ever be, as the law states, "worthy of respect in a democratic society, compatible with human dignity and not conflict with the fundamental rights of others".

The anti-Zionist theories he taught in seminars may not have envisaged this but Hamas has just demonstrated what trying to defeat the Zionist enemy entails: mass murder, rape, kidnapping, babies slaughtered in unspeakable ways. Anti-Zionism has a very different meaning this week from whatever it may have meant in the past.
