Today has been an offline day for me. However, I did find time to have a peek at a link suggested by Y.Ben David, who mentioned an article by Ernest Sternberg titled "Purifying the World: What the New Radical Ideology Stands For". I haven't yet had time to read it carefully, but at first glance Sternberg may have succeeded in tying together the many disparate strands of general nastiness that emanate these days from various parts of what we rather incorrectly call the "far Left". Whether they're Left or not, what they've got in common is a yearning for a pure, post-history world. Predictably, the two main enemies are the United States and Israel (previously known as the Big Satan and the Little Satan, if you remember your Iranian mythology).
There's a short online Sternberg lecture on the topic here.
Interestingly, Sternberg is a professor of geography, or urban planning, or something like that. You may remember that I wrote about his German predecessors of a century ago, just a few days ago. Apparently, some academic disciplines eventually redeem themselves totally.
