As a PS - this task I do is very hard - finding something good
   to say about people or groups I don't like. I also do the
   reverse: I criticize more harshly people or groups I _do_ like.
   I try very hard to reduce my own cognitive bias. Bias is
   impossible to eliminate, I believe, but finding "bad in the
   good" and "good in the bad" seems to be the only way I can
   temper it a little. Drawback: People think you're wishy-washy or
   don't make sense because you're not talking in clear "good
   guy/bad guy" terms.
