I would love to live in an enlightened world where we can all talk out our issues, without ever resorting to violence. I do believe that people, on an individual level, can be reasonable.
The problem <i>is</i> the masses. If a leader comes out with a compelling argument casting group X (country, terrorist cell, religious belief, etc) as a direct threat to the social group YOU belong to, you probably won't want to be the one who stands up and says "maybe that guys full of it?". You look weak and you look like you don't want to be part of the group. And the leader will tell you as much and try to push you out of the group.
Now, spin that story where there's a universal draft. All of a sudden, you and everyone else in the social group have to weigh the consequences of you or someone you love dying somewhere far away. When someone pipes up and tells the leader he/she's full of it, they don't sound like such a nay sayer.
In regards to just 'laying down and letting the terrorists kill you', I don't believe angersock meant that at all (correct me if I'm wrong) - we should avoid all this security theater BS. Do you really think that body scanners at airports are stopping terrorists? Any time I've flown into the states it seems like there's as many TSA agents as there are passengers.
