Antisemitism is vile, and needs to be stamped out. But is it worse in the Labour party than it is in any other party? Genuine question - I don't know. Has anyone counted up the number of incidents in all the political parties, judged their relative obnoxiousness and the overt and covert intentions of the instigators? Doubt it.
But Labour needs to be rid of it - no doubt about that. It is totally against the whole ethos of the party, and reflects badly on anyone who tolerates it.
