If anything, this fellow appears to be emulating Timothy McVeigh in pursuing his very strong death wish, and perhaps for similar reasons (though TMcV was silent to the end, while this fellow is endlessly running his mouth).
He also seems to have been very successful in stirring up the blood lust in a certain segment of Freeperdom, whose outlooks resemble his exterminationist view of the world in ways that might shock them if they ever paused to think about such things. In fact, I wonder if their only substantive difference with him is the identity of the group they wish to exterminate (as painfully as possible).

Conventional thinking is going to be ineffective.
