I have to agree to with Bronson. There's a certain gamble when your post is "being reviewed by your peers". If individuals with opposing viewpoints to your's are contemporaneously posting and are asked whether your submitted comment is "good" or "civil" and they don't agree with your viewpoint, it's easy enough for them say "no" and "no" and your comment is then relegated to the"uncivil" trash heap.

Although I don't always agree with Mr Kaahui's sometimes very pointed and loquacious viewpoints I'll always want to defend his right to express them.  His views that I don't agree with will often make me think hard upon the subject and possibly consider alternative viewpoints that don't flow with the status quo.
 
That said, I don't think I have ever seen where CB has clearly articulated the specific protocols of how a comment is ultimately deemed "uncivil".
