I, too, would like clarification of the good/bad/sorta classification.

Is a comment "bad" because it is disagreed with?  Because this is a site with a majority of posters of a more liberal mindset, are those posts that disagree with that point of view marked "bad" - thereby relegating them further down the chain?  Is it a form of censorship?  What exactly makes a comment "good" or "bad"?  

I think one deserves the right to refute a "bad" rating - or at least to know the reasons why.  Would not a "dislike" marking be a more fair way to proceed?  The "civil" judgement seems to be sufficient to the purpose.
