I sent the comment below to the Socialist Worker, if they respond or post my comment I will note it on this blog.
I enjoyed this article but I must say I am puzzled by some of the wording. Reading this one would get the impression that Parsons was the only anarchist of the eight. They all were! The labor movement in Chicago, leadership and rank and file, was dominated by anarchists. Spies' The Arbeiter Zeitung was as anarchist a paper as Pouget's or Most's. The quote from Spies is decidedly anarchist.
Why doesn't the author want to acknowledge this? It's deceptive. There is much too much sectarianism on the left! The author grossly inflates the role played by socialists and diminishes the role of anarchists in the worker's movement, at least as it relates to the Haymarket affair. Shame on her, and on the Socialist Worker. You have distorted history just the way the bourgeois media/textbooks do. If you want to help workers, tell them the truth about their history.
