Rag,
I know when I was a child "piccanniny" was understood to be a racist expression.

No it was not.
Your memory or honesty are at fault.
I have produced an old Mudcat thread to support my asserttion.
You will never be able to produce anything because your assertion is bollocks.

I think you will find professor that I have never mentioned Naz Shah, not once, not ever.

True for once Rag. What you did say was,
"If you do not recognise the term "piccannines" as being racist (which even Bobad accepts) you are an abject racist."

So by your logic, "If you do not recognise Naz Shah's bile as being anisemitic (which even Shah herself accepts) you are an abject antisemite."

See what I did there Rag?
Now, both Steve and Jim denied that her statement was antisemitic, but she herself, the NEC and the Party agree it was.
That makes Steve and Jim abject antisemites according to you then Rag.
