Now I understand media "bias"

Assume that politician Smith does 5 good things and 2 dumb things and that politician Jones does 2 good things and 5 dumb things. According to some letter writers, the "media" is "biased" because it commented unfavorably on the 5 dumb things that politician Jones did. It is irrelevant to these letter writers that it also commented unfavorably on the 2 dumb things that politician Smith did.
