Until now the party has shown good unity under Starmer. If you want to foment disunity you can do it in the disreputable and opportunistic manner that Starmer has just displayed. Not an especially healing move, was it? And there is a bottom line here: Maxine Peake's remark may have been inaccurate but the broader picture of Israel indulging in the training she spoke of is true. That was a criticism of Israeli government policy. Therefore it was in no way antisemitic, not even remotely. Starmer wanted Becky out and he used this false pretext to do it. Perhaps you'd also approve of him selling his own kids in order "to make himself electable..."
