The video has speaker Brendan O'Neill in which he argues (I think effectively) that the Political Left in Europe especially has become conspiratorial and to a great extent a promoter of Anti-Semitism in the process.
The line between criticism of Israeli policy and Jews are now completely dissolved. For example now often people will go to great length to emphasis that "Israeli's love slaughtering children!" which is an odd accusation since no other warlike State is accused of such a thing, I've never heard China, North Korea, or really even ISIS, ect as being explicitly decried as thirsting for child blood. Of course there is a dark similarity between this charge and the claim that Jews used to eat christian children or use their blood to make Matsa. This is also never said about Britain during its worst Imperial exercises, or the United States in particular.
Or Israel controls western politics and or banking, just look at Ad-Busters, a respected Leftie media outfit that ran a rarely spoken of article basically labeling which senators are Jews. Much akin to the claim that Jews run the governments. Or that Israel is the source of global instability which is a popular belief among Europeans, freakishly similar to the belief in bygone centuries that the Jews were cause of social strife and instability.
I think its fairly compelling, has the Left or in general anyone but Brendan focuses on the Left since that is the locus of Anti-Israeli activism, become somewhat fanatically conspiratorial and Anti-semitic? I think yes, though I suspect this will not be without controversy.
