The whole subject of violent revolution is difficult and dangerous to study or discuss. This is not a new thing, either.

In college, I took a graduate level course called "War and conflict in Latin America". It was team taught by two people I respected, Perez and Nesman -- the first a firebrand cuban with revolutionary links, and the other the son of an industrial family who were enriched by their links to the State Department in Cuba under Batista. Great friends, great counterpoint.
The course was actually about the circumstances that led to violent revolution in Bolivia, Mexico and Cuba, but the university let it be known- very directly- that the use of the word "revolution" in the course description would cause the course to be canceled forthwith. That was in a far more tolerant time, in 1979.  
In the Empire of today, such topics carry a high risk of getting anyone who attempts to write about them on multiple "Bad Lists". It is foolish to think that "Well, I have nothing to hide-- they won't mess with me just for talking about it." They will, and they have legal suypport, thanks to Jane Harmon, D-Calif.
As anyone who knows me will attest, I am not shy about such discussions, on-line or in person.
I think in the end real change will be violent, --or it will not happen. I also think the mechanisms for derailing such events are far better planned and applied than ever before. I have said this many times, in many venues. I too am not very hopeful. But I talk, I write, I print shirts and picket, I tell the stories of my heroes, like Erin Watada---
The last time I traveled to the US I was detained, isolated, strip searched, interrogated, threatened---and eventually released. In the end, they said it was a case of mistaken identity-- that there was someone with the same name who had a local warrant out for non-payment of child support.  Right. This after an international flight, a current passport and driver's license for id, etc. etc.
I said as much, and the unidentified officer (?) who "spoke" with me said, "Well, Mr Miller, perhaps there is a lesson to be learned here."

I will not be cowed, and I hope we follow this trail of ideas until it peters out, or until we create something good. With awareness.

Capitalism searches out the darkest corners of human potential, and mainlines them.
