There are so many...
MikeyDB - combination philosopher, sociologist, and cynic (as well as a writer). He isn't afraid to provide though provoking rebuttals and theories.
Zzarchov - a centrist who will accept and provide argument from any non-extremist angle.
Unclepercy - not your typical uncle. Just ask her.
Missile -
MMMike - been pretty quiet lately. He's hanging out in the weeds ready to pounce.
Logic7 - Our resident 9-11 cynic. Not afraid to duke it out from the conspiracy side.
Wallyj - has more brains than his avatar. Not a Bush fan but is not afraid to speak up for Americans.
Jimmoyer - I think he's down the southeast coast. Strong on ethics, philosophy and literature.
Johnny Utah - drops to take a swing at lefties every once in a while. Has a big heart and cuts to the chase.
Stretch - I think he's in Aussieland. Has some interesting angles on controversial issues.
FiveParadox - The parliamentary expert. He will no doubt be governor general some day (being the last guy in Canada who knows what the formal responsibilities are). Often very colorful posts.
IArtthere4Iam - likes to talk politics on occasion.
Karlin - likes to duke it out with the right
Darkbeaver - missing in action - another who fights back rom the left of centre.
Walter - I have to check out more of Walter's posts, I don't cross paths too often.
justFred - same with Fred
...the mid term exam is next week ;-)
