1) call the police
2) meditate and send loving thoughts to your rapist
3) hit the rapist with a crowbar
Myself, I would choose #3.
Ends justify the means?
Re what I should've asked about supporting the Iraqis against imperialism: Go ahead and answer the question I actually asked. Do the ends ever justify the means? Do they justify the means in the case of Bush's invasion of Iraq?
You ask if it's legitimate for the Iraqis to fight back? Well, at first it was understandable and predictable. When the US was acting as an occupying force, was taking sides in the internecine warfare, and didn't have the approval of a legitimate Iraqi government, the reprisals even may have been "legitimate."
But things have changed. Now there is a legitimate Iraqi government asking for the troops to stay (for another 16 months, at least). And the US is (more) clearly keeping the peace rather than taking sides. If it was ever "legitimate" to kill Americans in self-defense, that rationale has disappeared or is disappearing quickly.
And again, we're not talking about defending yourself or your land. We're talking about defending trees that don't belong to you, as you've admitted. Since there's no self-defense in this case, there's no legitimate excuse for violence. Not until you've explored all other options, anyway.
Gandhi, King, and the pope
Re my quoting the pope: Pope John Paul II didn't countenance the slave trade, collaborate with the Nazis, or molest children. The fact that his predecessors did bad things doesn't implicate him personally. Therefore, your comment is irrelevant.
I've already told you what the rational solution to your problem is. Here, read it again: nonviolent protests, boycotts, and other concerted actions. These techniques worked for Gandhi and King, so they should work for tree-huggers. If they don't, then we can consider hitting the "rapists" with crowbars.
Re "you have no idea what it means to love something with so much passion": Spare me the amateur psychoanalysis. You love your self-justifications for committing violence. I love peace. I suspect I'd defend seeking peaceful solutions as passionately as you'd defend beating and killing people for the sake of someone's trees.
Re my debunking of the frat-kid e-mail: Are you a tree, bright boy? Unless you are, you have no excuse for committing violence against people who "rape forests." Again, self-defense means defending yourself, not defending someone else's property. The sooner you learn that, the better.
Bin Laden, Bush, and you
Everyone who commits violence first thinks they have a legitimate reason to do so. Hitler, Bin Laden, and Bush did and you do too. In terms of stupidly rationalizing your thuggery, you're just like them.
Nonviolent protests--including words, letters, and blog postings--have had an effect in countless causes. They've succeeded many times when violence wasn't necessary and probably would've been counterproductive. For instance, they've convinced people to start taking global warming seriously. They've coaxed courts to legalize gay marriage in some states. They've eliminated Indian mascots at hundreds of schools.
Clearly you need an education in nonviolent methods of protest. Give me a situation where you think violence is necessary--a situation not involving legitimate self-defense--and I'll explain why it isn't.
