Underneath the personal attacks and vitriol that have dominated Twitter this week, there are important political differences between left and right approaches to combating antisemitism.

The British Jewish community would do well to have real dialogue about those differences.

The right's approach to combating antisemitism centres on security. We cannot stop antisemitism but we can protect ourselves against it. Good security walls protecting our synagogues. Friendly relations with police. A strong Jewish state with a strong army and tight borders.

The problem with a security-based approach to combating antisemitism is that it is necessarily inward-looking and exclusive. When black people are turned away at the synagogue door, that's not a side effect: that's the system working. When Jews become paranoid, that's inevitable.

The left's approach to combating antisemitism is totally different. It is based on a politics of emancipation. We get free by fighting for freedom with others. We campaign explicitly against all oppressions: we destroy antisemitism with racism, Islamophobia, transphobia, etc.

When the left ends up in coalitions with people who have said antisemitic things, or who have reactionary views totally at odds with our stated values, that's not an accident. That's precisely the strategy. We work with people to raise their consciousness on a long journey.

The security-based approach is more popular because it delivers on its aims in the short-term. People feel safer, and probably are.

The left's project is a harder sell. It involves lots of discomfort and long-term engagement.

But ultimately its rewards are far greater.
