Ann Coulter is like Sarah Silverman if she were a Republican comedienne: Deliberately offensive in an unprecedented way, but she speaks with such an oopsie flair that the charming innocence of her delivery trumps the rhetoric with its ironic positivity. Her brazen intolerance is her sustenance, so she says anything she wants and receives free air time while the republicans try to benefit from it because the people don't see many democrats fighting back.
This situation is similar to Tim Hardaway's comments a few weeks ago, in that I do not care about Tim Hardaway, but rather the underlying attitudes that he broadcast. John Amaechi, about whom Hardaway spoke, was actually glad Hardaway said what he did because it finally meant the presence of public, high-profile bigotry and hatred couldn't be denied anymore. Coulter should be similarly thanked (not the right word), because her crass marginalization has at least opened the door for discussion. It's still sad that her use of a term to dehumanize and disparage, whether or not it was used entirely in the pejorative, was met with cheers and applause. There's already a Time Magazine article that touches on the circumstances if her slurs were racially and not sexually oriented.
In some aspects I'm fine with putting her in the spotlight instead of burying her; she probably did more damage to her party by alienating a larger group of undecided moderates.
