I too puzzle. Hadn't known anything about the "warning system". I may have only noted two posts as "uncivil" - and they really were. It is my suspicion that when our resident fundamentalists happen upon your comments they auto. tag it. There are enough, I suspect, to manage that. 
I for one do NOT want you gone, any more than I would a Steven Colbert or John Stuart. 
If you are excluded and "they" stay, then CIVIL is not a friend to any of us.
