Your example isn't a good one, because there's no credible reason for anyone to believe that an anonymous Slashdot poster is going to be able to launch an air attack on US military base. A threat by a lone individual to carry out a mass murder, on the other hand, is perfectly believable, because they happen with some frequency.
And making threats is not protected free speech, so it has no implications in that regard. Calling this a "perceived" threat is disingenuous on your part -- it's a real threat, plain and simple, whether or not he intended to act on it.
