I don’t doubt that many Jewish people are put off voting Labour because of the antisemitic actions of some of its members, and the leadership’s seeming inability to control or remove those people. Plenty of non-Jewish people are put off by it too.

There are two things I don’t understand.

If there are antisemites in Labour (which, again, does seem to be the case): why and how? Who are these people that have joined a party of the left, a party that has always been anti-nazi, anti-racist, pro equality and human rights — who join it, and yet stand in direct opposition to its core values? It’s like a climate-change denier joining the Green Party.

Further, why now? Why has this blown up in the last couple of years? These invasive members presumably haven’t just joined the party. It’s hard to imagine that they joined because of Corbyn being the leader.

Unless that’s exactly what it is. Maybe Corbyn’s seeming weakness on responding to the problem. and/or a willful misunderstanding of his stance on Palestine and the government of Israel, has attracted such people to the party. In which case — in any case — the obvious thing to do is to find them and eject them; just as they can easily eject members who suggest voting for another party.

I see that The Guardian has published an “everything you need to know” guide on the matter. Which is good, but it doesn’t really answer my questions.

Corbyn has spoken out against antisemitism again. He may have appeared vague on Brexit, but I don’t think he could be any clearer on this.
