(1) This person has been around FR long enough to know who's black, Jewish, evolutionist, etc.
(2) Paleocons are anti-evolution, anti-Israel, overtly concerned with nonwhite immigration and many are just one mutation away from being drooling Stormfronties.
(3) While antisemitism/racism would efficiently push FR's hot buttons, coming out against evolution would not.
(3a) FR has a strongly perceived racist image outside the conservative community.
(4) This started all of a sudden in April.
From (3) we can deduce that while he is trolling, he also believes in what he says. From (3a) we can also conclude this person is right-wing...else he wouldn't know that racism pisses us off.
From (1) we can further conclude that he is/was an active Freeper, and putting together (2), we can conclude he was a paleoconservative. However if he were a longtime Freeper why did he just start stalking after years?
I believe something happened to piss him off in April, probably a banning. That kind of anger makes me suspect he started doing this only a day or two after he was banned. So, if I were JR, I'd search through the registry of Freepers that were banned within a few days of the first stalking and match up their ISPs (most paleocons can't be smart enough to know to switch providers).
good points
Some of these people return, several times, and get re-zotted when they're identified. So even if his latest zot were in April, it could still relate back to a much earlier incident. Or, as you suggest, it could be specific to April.
Because I was singled out to get 11 of those posts, somewhat early in the game, I'm very suspicious that his original zotting arose out of his anti-evolution and anti-science attitudes. If I'm right, the racial and religious stuff he's now posting is just window-dressing (or additional hangups that he's tossing in because he can't control his urges). I'm sticking to my suspicions because the science threads had serious problems with a few truly disturbed people back in July-September of 2003. But I suppose there are others I'm not aware of in other threads.
I would guess some of us are just random names.
