How Do You Distinguish a Troll or Poe from an Idiot?

[Cinjin]

From appearance, it seems as if the staff ban some members with radical viewpoints (such as BGChuckLee and Al-Fatifha) that conflict with those of the majority of this community, and many of the staff indentify these people as trolls or poes. Yet, how do you distinguish a troll or poe from a radical?
I'd really appreciate answers from the staff of the community.

If those with radical alternative views were banned arbitrarily as you suggest, we wouldn't have a theist on this website.

Trolls, poes and idiots are all lumped together. It matters not, and I will go ahead and clarify the way we as a staff operate: If you continually break the rules, you get banned. Clear now?
