I don't think that Corbyn is anti-semitic. I think that his biggest problem is that he is a campaigner, not a politician. Because of this he is most familiar with activists, surrounded himself with them, allowed them to run riot and was unable to draw the diverse sections of the LP together.
The criticism that seems to be most strongly coming from the report is that the party's procedures for dealing with anti-semitism were chaotic and ad hoc, which let people get away with a great deal and didn't give confidence in their procedures.
That he is not a politician is, for me, evidenced by his statement today. He should have just kept quiet instead of more or less saying that it was unfair because he thought that the accusations were exaggerated. Starmer could hardly let him get away with that when he himself had just stated that there should be no excuses made for the past. I do actually think that Corbyn is probably correct, but he chose absolutely the wrong moment to say it.
My twitter timeline is full of pros and antis, which clearly reflects current feeling.
I equally don't believe that Starmer is particularly right wing. Dealing with the anti-semitism problem is not anti socialism.
I think it's interesting that some of the criticism of the current government is that it consists of campaigners, which is why it's chaotic and seems to have no clear strategy or concern for the country. They can run a campaign, but not a country. Corbyn is a great campaigner but he can't run a party.
