Context: Luigi Galleani was an Italian Anarchist, who advocated for 'Propaganda of the Deed' - radical, direct action (political assassinations, bombings, etc).
He was arrested and exiled numerous times for his insurrectionist and anti-war views. Eventually growing disillusioned with labour movements and unionism for their reformist approaches. His followers were known as Galleanisti and were responsible for acts such as poisoning hundreds of high profile industrial/finance/law figures at a banquet a la the Red Wedding, attempting to bomb John D. Rockefeller, fighting in the Mexican revolution, bombing Wall Street, among other notable acts of resistance.
Ye I'm not sure I agree with that interpretation of history there. From what I've read it was a counter productive tactic as far as spreading anarchism was concerned
In many ways we're still rehabilitating anarchism's image from that era. I don't think we should eliminate propaganda of the deed entirely, but we have to accept that it requires careful planning for how it will appear to the people when it's enacted
Mangione shows that there can be strong public support for it.
The decider is who gets to do the messaging around.
