Of course, The Millitant blaiming the capitalists for the shooting is as stuipid as blaming guns, video games, Marylin Manson &c,
Actually as I read it the only thing The Militant directly says about why the shootings occurred was that Lanza was mentally ill. They don't attempt to assess why he did it other than that.
The point of the article is not about the shootings so much as the reactionary response to them from conservatives and liberals.
The point they make about capitalism being a violent system across the board is valid. When the President gets dewy eyed about the over 3,000 "victims of gun violence" in the U.S. annually but has nothing to say about the over 4,000 deaths on the job annually in the U.S. the hypocrisy level increases some. To cite one example.
