What you are missing, Confused Of Dagenham, is the deliberate offensiveness of the choice of vocabulary in which Mr Carroll insists on denouncing Israel ~~ a never-ending litany of terms like Nazi & Holocaust, of particularly distressing and offensive associations to Jews. It has been suggested that he find other terms to express his opposition to Israel, but he has declined to do so; which suggests that his purpose is to be offensive to Jews; which I cannot envisage as the sort of course that would be deliberately pursued by anyone who was not a hater of Jews in general ~~ an antisemite, in short.
