If I have been critical, it is because I believe it is my obligation to do so. And as a matter and duty of conscience, the notion that one should stay silent - and as the norms and values that keep America strong are undermined and as the alliances and agreements that ensure the stability of the entire world are routinely threatened by the level of thought that goes into 140 characters - the notion that we should say or do nothing in the face of such mercurial behavior is ahistoric and, I believe, profoundly misguided.
