I recently read an incredible novel by Philip Roth called 'American Pastoral', set in New Jersey during the Vietnam war, and watched a film called 'The Baader Meinhof Complex', which is based on real events and tells the story of the Red Army Brigade, a faction of left wing terrorists active in Germany, primarily during the seventies.

I don't want to give too much of the plot of the novel away, but it comes at it from the view of the father of someone who resorts to violence, to terrorism basically, and it's pretty heart-wrenching, seeing his agonised bemusement as to why this has happened. He represents the 'establishment' side of things, but the telling thing for me is that he is the one in the novel with whom I have the most sympathy, not the 'revolutionary' youth. Similarly, in the Baader-Meinhof film the terrorist gang are protagonists and sort of anti-heroes, so you kind of feel sympathy for them, but the stuff that they did is straight up wrong as far as I'm concerned, and fairly horrendous at times.
Also, violence is not cool. It doesn't solve anything. Music solves, if not everything, then some things at least, for sure. I actually ended up watching 'The Baader-Meinhof Connection' because of my general interest in German music at the moment, which come to think about it, is what I should be telling you all about, and is probably way more interesting. Oh well. Soon.
