Jim,
Why is suggesting the killing of Jews a year or so before six million were exterminated "silly" ?

That is what made it anti-Semitic. The rubbish doggerel made it silly.
It certainly did not count as evidence of your ludicrous claim that the British establishment was riddled with anti-Semitism, or justify you in claiming a quote that you had just made up? That was my point at the time.

Now, I am here to discuss current issues over Israel, not to argue over things said in unrelated threads many years ago. That is a tactic you always revert to when you have lost an argument.

PFR,
I seriously doubt you are the best qualified most credible self appointed arbiter
of what is a serious contribution to a mudcat BS thread...

OK. produce one serious contribution you actually have made.
Installing bouncy castles and petting zoos on the border?
