Link to an article by Pavlina Tcherneva:
A takedown of Henwood is a bit like shooting fish in a barrel, given that he is so weak on theory and is one of those insufferable centrist journalists posing as a leftist — much like Naomi Klein or Paul Mason. But still, somebody had to write the takedown. Sure, Henwood cites some true facts but the main point Tcherneva gets across is that Henwood is being exceptionally petty and obtuse by focusing on trivialities and individual personalities. He is clearly engaging in a highly superficial smear job.
