The system is flawed.  It relies too much on opinion and I believe some people rate comments "uncivil" according to beliefs rather than their actual civility.

I'm not sure I've ever actually agreed with anything political that you've ever said but you seem civil at least.  And the commenters here at the Denver Post mostly seem to disagree with you as well so it wouldn't surprise me if some people rate you "uncivil" as a form of disagreement but I am careful not to do that.

If I disagree strongly enough I can simply reply to you rather than calling you "uncivil".

I got a "final warning" earlier for rating a comment as civil. It was borderline civil and I don't think it was yours.  I even disagreed with it, but that doesn't make it uncivil.

it's an interesting concept they have, but it is seriously flawed.
