if Labour is guilty of the accusations made against it what form does that antisemitism take and why is nobody prepared to describe it?

Why do we need to? I do not even care, but there is no doubt that Labour has a serious problem because all those people say so.
Or do you believe they all lie against their Party like you believe the deputy Leader does?

You've given this excuse before Keith and followed it with your antisemitic suggestion that they did not describe that antisemitism publicly because of their love of the party

I am sure that they all love their Party.
When they experience anti-Semitism within that Party, or any other kind of discrimination or intolerance, the standard thing to do is report it to the Party and let them deal with it.
