Your last point is wrong and I don't think you should assume those are my views. Behavior in concentration camps should obviously be policed, because it's significant and not recreatable and should therefore be preserved as a place for the people it is significant to. A privately owned printed book is not, so you should be able to attempt to piss other people off by burning it, if that is your perogative. If we're getting specific, I don't think you should be allowed to start a fire anywhere near buildings you don't own, unless it's to light a cigarette or w\e
Other than that, I agree you should find a civilized way to express your beliefs, but we shouldn't, for good reasons, police the way people express themselves. A law like this sets a precedent for religious organizations; that they can have their way if they (re)act violently. It will lead to more violence down the road so we need a better solution.
intent to piss off is not intent to harm. you are not being harmed by being pissed off. it is not harmful. in a civilized society, claiming harm from a book burning is called being a little piss baby. they should grow up
