Ideology without room for common sense is dangerous. Your extreme example cannot be used to justify one group with something to gain, minipulating a vulnerable group to commit violence. For example, I remember a few years ago there was a 15 year old suicide bomber at an Israel/Palestine checkpoint who didn't blow himself up. Either his bomb malfunctioned or he changed his mind, but either way he was caught and questioned. Turns out he was not very religious or political, just scared of getting in trouble because of bad grades at school. He was recruited by an older man who preyed on the young and vulnerable for his own political ends and convinced this boy that a bomb would fix his problems. Don't tell me this older man's free speech should be protected. He may not have strapped the bomb on himself, but he is an accessory to attempted murder nonetheless.
I say, thank you, Anonymous. They have the balls not to be paralyzed by self-righteous navel-gazing.
