I eagerly read the link, expecting to find all kinds of anti-semitic quotes and remarks, and the only reference to anti Jewishism is attributed to some reporter/photographer who allegedly heard someone shouting "Tory Jewish scum".
Shock! Horror! Now that's dreadful, at a demonstration with thousands of pent up nutters, to hear such offensive words is really unexpected, innit? Not!
In short, therefore, no one has a clue who, if anyone, actually uttered those words? It conjures up a silly scenario where you can imagine some neanderthal demonstrator trying to think up something horrible to shout:
"Mmmmmhhhh, let me seeeeeee..........ah, yes, got it! He's a Tory, and I hate them!.......Oh, yeah, somebody said he was also Jewish......I hate them as well! So I'll insult him by letting him know my prejudices? He'll never get over that, will he?"
Duh.........................
