Waste of a jail resource, but I have no sympathy for him. He'll probably serve less than a month. He was aggressively inciting people after the incident in a way that would have endangered himself before long. He needs teaching a lesson about what we will and won't accept as a society.
Americans, quit the judgemental crap. You tolerating obnoxious inciteful racists doesn't mean we have to. We have specific laws against airing this kind of venomous hatred, purely because its corrosive to society and doesn't serve a purpose. We have free speech, we're just more pragmatic about what we consider constructive free speech. He wasn't trying to make a political point, or stating anything even possible to be an objective viewpoint, he was just spewing hatred, ratcheting up tension on the Internet and calling all sorts of people racial epithets and cunts. He can say whatever he wants privately, but when enough people are upset and angered, complaining to police - we reserve the right to punish horrible gobshites.... again, its not a jail issue, and this is a waste of a resource, but he deserves something. He deserves his head kicking in, quite frankly. I'd have preferred that.
