Dave,
Have you considered that it may be your mind that is closed to the idea that the Labour party is no better or worse that the others?

Yes Dave, but there is no case.
All parties have Jewish members, but it is only those in Labour who have been reporting anti-Semitism.

There is ample evidence for Labour having a serious problem, but none at all for any other party.
If you know of any please share, but neither Steve nor Jim have come up with anything.
I know evidence is important to you so you must take seriously the complete absence on one side against the plethora against Labour.
