So what. Free speech kills, we knew that. The lack of it kills more. Blame the murders on the murderers.
It should be allowed, but is it, or can it be, right to burn the Koran? In general I have contempt for those who deliberately insult what another holds dear. The fact that I uphold the right to say anything should strengthen, not weaken, my willingness to judge what is said. I despise Pastor Jones. I despise the members of Al-Muhajiroun whose insults to dead soldiers gave birth to the English Defence League.
However now that Jones has burned his Koran, and it has led to murders by Muslim fanatics as he must have known it would, I now see an argument that further murders will be made less likely by further burnings. If they keep happening it will have a desensitising effect.
Yet I still think burning someone’s holy symbol is a contemptible act. To hurt a group (and hurt feelings are a form of hurt) because some of its members are bad people is just another instance of the collectivist error. I would not do it. I suppose what I am saying is that given that it will happen somewhere in the world fairly regularly, this fact should be publicised. Eventually the mobs will get tired of assembling yet again.
