Sarah Palin and the teacher.

Here's your background reading. I just want to say that it's stupid as hell to say that someone working on the terrific musical "Hedwig and the Angry Inch" is "a singer in a transvestite band." What tastes like red meat to some people mostly makes you look small-minded, nasty, and uninformed. And going after Kathleen Gustafson on the ground that she's "not a teacher" when she works in some capacity in a school is like going after "Joe the Plumber" because he wasn't a licensed plumber. What you've got, in both cases, is an ordinary citizen who encountered a politician in a way that yielded some viral video. That revealed whatever it revealed about the politician. Trashing the private citizen is mean-spirited and likely to backfire.
