Bingo. If organizations like your average White Supremacist group or the Westboro Baptist Church aren't going to jail for 25 years because of the vile (and often times very much threatening) garbage they spew, then neither should this guy. Can't have it both ways.
Granted of course he SHOULD get some form of punishment, but let's not anyone kid themselves; the only reason he's getting the legal equivalent of a sledgehammer to the face instead of a slap on the wrist is entirely due to the abject petrifying horror that the specter of 9/11 still inspires throughout much of North America. As an overall society, we've far from gotten over that and are mentally and emotionally still kinda going through the "curled in a corner in the fetal position whilst sucking our thumb and thinking happy-happy thoughts" phase. It shows blatantly in the kinds of legal bias you see in cases like this: threaten someone's life in a general sense, and it gets treated like a misdemeanor. Threaten someone's life using anything that reminds anyone in the slightest of anything even tangentially related to 9/11, and the panic button is instantaneously pressed and we're all but ready to lynch someone.
I'm sure as hell not saying that what this guy did wasn't horrible or that he shouldn't face any kind of punishment for it; but this is blatantly overkill, and we can't completely freak out like this from now till eternity every single solitary time the words "Islam" and "terrorism" are used the same sentence. What NightSpirit said earlier was right on the money: this guy's clearly just a "wannabe". He's an idiot teenager, not a threat to national security. If we're gonna put a nitwit like him away for 25+, we may as well do the same to every other idiot teenager that says or does something monumentally stupid (not entirely a bad idea now that I think about it, but that's neither here nor there). People that have committed far worse crimes that were directly responsible for ruining and/or ending lives have gotten off with lighter sentences than this. This wasn't justice being carried out or anyone's safety being protected: this was some loudmouthed schmuck being made an example of in a matter that is still very much a hot-button political issue.
I guarantee you that if this same kid pulled this same crap in the 80's or 90's, the most he'd get is he'd have to pay an extremely severe fine, maybe (maybe) do some fairly light jail time, followed then by so many months worth of counseling and community service, whereupon he'd then get sent home where mom and dad would ground him for a year and take away his keys to the family Chevy. I'm not trying to downplay how horrible 9/11 was or how much of a very real threat jihadist terrorists are; I'm not even saying that some of the events of the last decade shouldn't have in any way lit a fire under our butts to up our national security measures. But when we get to the point of locking up our own kids for half their lives just for saying and doing something idiotic, it by all means ought to give us pause and think for a second about how far we're taking this and how much we're letting that horrific tragedy in downtown New York 10 years ago get to us and change us for the worse.
We dearly, dearly need as a country to calm the hell down. If the main goal of Islamic Fundamentalist terrorist groups was to inspire fear within us as a nation, then we may as well wave a white flag and surrender now because they've already long ago won that particular fight.
