Who is (was) he? I’ve never seen him until this rather odd thread..
If you look at his posting history, you’ll find that even though he was from 1998, the first page of posts goes back to 2002. Apparently he was some sort of sleeper.
Why he decided to flame out at this point, who knows?
Being an insufferable jerk was a good start, and insulting Jim and the military was the big finale.
