That's what I mean though. I get that they're cannon fodder, but why would fodder make such good hitmen?
I can only report for the German terrorist cells of the 1970s; these guys regularly trained with Arab resistance groups. The very same people that blew up german politicians because of their nazi past trained with antii-israeli terrorists and, during an airplane abduction, separated out and shot the jewish passengers.
So it looks like hippies make good cannonfodder because
a) they don't realize they're being used
b) they don't realize they're basically just slightly worse than the people they claim to be fighting,
c) they can be militant enough, especially in fringe sects like PETA and similar, to spend quite a lot of time and resources in preparing whatever "action" their leaders demand.
Not that nazi idiots are any better: If a young arab attends a camp where uniformed militants sing songs that oppose the constitution, glorify murder(er)s, practice with assault rifles and so on, he'd probably wind up in prison as a suspected terrorist, silenced with gaffa tape and with a 220 volt cable around his genitals.
If a young Nazi attends such a camp and is dumb enough to have himself photographed showing nazi greetings while uniform-clad skins march past wielding assault rifles, he can later succeed Jorg Haider as the head of Austria's so-called Freedom Party and joke about "playing paintball".
