My point there,Keith, wasn't whether Jackie Walker knew that Holocaust Day is, officially at least, about all genocides. It's that, so far as most people are concerned it actually isn't. And insofar as that is the case, it needs to be challenged. If Jackie Walker was challenging that failure to get the message across, that would be perfectly reasonable.

As for the fact that her expressing confusion about how antisemitism should be defined, the extended detour this thread has made indicates very clearly that there is indeed confusion about this, and about how far the term can appropriately used in respect of attitudes towards the Israeli government and the State of Israel, rather than towards Jews and Judaism.

It strikes me that when Jews who challenge such an extension of the term are attacked as "self-hating Jews", that is itself at very least extremely close to being an example of anti-semitism.
