He's just pointing out that he did refute the claims, where you (in the comment directly above), claim that he refutes the persons character but did not refute the claims.

To refute apparently can mean both /prove/ and just /say/ something is untrue.
The way I know the word is in the sense of "proving", not just saying. I dare to say that is the way most people would use that word.
Giganews only /says/ the allegations are untrue, it doesn't /prove/ that. To me it means poster is correct in stating their is no refuting of the claims, and I guess it's the same for most readers.
