Yes, most likely. What’s striking for me is that the anarchist charge is the go-to indictment for the FBI in this case. Reading the indictment, you get the sense they think it is the most damning.

Those causes are certainly sympathetic to anarchism, but I'm pretty sure that the early 20th century anarchists really were anarchists. They were pretty open about their goals; just like the people we currently call terrorists.

Libertarian socialism is now the most polite label for the anarchist political philosophy. http://en.wikipedia.org/wiki/Libertarian_socialism I prefer to call it left libertarianism.
