Last post (sooo distracting!) - I have been doing some reading recently about the Anarchists - who were around at the turn of the 19th C. It's easy to forget that in those 20 years, 6 separate heads of state across Europe were assassinated by Anarchists. There were also quite a lot of random attacks, bombings, stabbings, slashing the horses of wealthy people and so on.
I think there are some parallels between the Anarchists and Islamic fundamentalists.
The Anarchists were extremely poor, poorly educated but auto-didacts - desperate to learn and easily led.
They believed in a secular utopian vision of how everyone would be (somehow?!?) galvanised by their Deed to rise up and create a world in which everyone shared everything.
They formed little cells.
They usually gave themselves up after committing their Deed, knowing they would always face the death penalty - they needed the martyrdom in order for the Deed to inspire everyone.
They followed secular preachers of Anarchism - men like Prince Kropotkin - who gave salon speeches about how violence and hate would produce change, listened to by intellectual worthies like George Bernard Shaw, who probably felt super cool and liberal by listening.
The British government took quite a long time to do anything about stopping the hate "preaching", given the number of assassinations etc
I suppose the interesting point is - everything comes around - especially if you (even if accidentally!) recreate social conditions.
