What about this? Does chasing a Jewish family out of town with threats of violence in order to intimidate or coerce a civilian population not count? And how about this? Does bombing abortion clinics and killing doctors who perform abortions not fall under this definition either? Sounds like the same religious extremists to me that are always cited as the "crazy bad evildoers". Oh wait, I forgot, sorry - these people don't have brown skin so they can't POSSIBLY be classified as terrorists.
What about the whole "anti-government thing" in the definitions above? Need I even mention what happened in Oklahoma City? Oh, never mind that one. Or what about the motivations of the Unabomber? How about the anthrax attacks in late 2001? Not enough? OK, fine. Remember the Olympics in 1996??
No, we don't have any domestic terrorism to worry about. We don't have to worry about standoffs with white supremacist groups or any government separatist groups. And with the way that the laws are enforced nowadays, it doesn't take much to qualify as an "enemy combatant", regardless of where you are or what your intent is. Or maybe even what you actually have or have not done. Or snipers in Maryland whose background and motivations are, shall we say, interesting?
And what about those seven "domestic terrorists" in Florida? Even though it looks more and more like their plans were more like pipe dreams. But we don't have this problem here? They aren't "here"? Please, spare me the histrionics.
Or, how about some of those who actually are promoting bombings and killing of innocent people here in the US? You know, like wishing that the NY Times building would be blown up? Or that Al Qaeda should bomb San Francisco? And just for shits and giggles, what about saying that someone should poison a Supreme Court Justice?
Oh, I see. IOKIYAR. No harm, no foul. You were just kidding. Well, that is just great, since others aren't quite so lucky even if they weren't guilty of anything other than mispronouncing a word in a foreign language. They get rendered and tortured. You get to spew more hate and attempt to incite violence against a group of civilians in order to coerce them.
David Neiwert's blog is one of the best resources I can think of on the topic of our own home-grown terrorists, and he's pointed out throughout the past several years that the face of much of our terrorists is white, extremely right-wing, and nominally Christian. It doesn't help that our own military is training a new generation of white supremacist terrorists in the art of urban guerrilla warfare.
