I am more frightened by the poll questions you cite that show the majority of Americans now believe that every point of view has a political purpose. That every objection spoken intends to advance a political agenda. That every attempt to show cause is an attempt to shift blame and is met with scorn. How can there be honest debate, if no view is thought sincere, and all words are labeled as duplicitous?
Whatever your view about the relationship, direct or indirect, of words to the violence in Tucson, the words that discuss the events are chilling. The lingering innuendo that the tee shirts at the memorial were tied to the Democratic Party, the twitter posts I read that urged folk to label the gun man as being on the “liberal left,” the suggestion that the memorial was “inappropriate” because it celebrated life with applause—all these words are actions that do violence because they question our sincerity and seek to diminish our humaneness and honesty; they cynically limit our motives and assign dubious purposes and demeaning calculations to every single expression we share. Right or wrong, we are moving to make every utterance a perfidy–an act of treachery that violates our trust and deliberately breaches our faith.
