In any threat situation fear exists. Fear of death and manner of death, of pain, of confrontation, of shouting bearded men from an alien culture. Fear exists and is useful. Fear of islam / sharia / jihad is not a phobia. The reaction is the key... cowardice is a common response, however bravery, action, insight, leadership are also possible responses to fear.
The other part of response is our lack of belief in ourselves, perhaps even an understanding of why we are not Afghanistan or Somalia or Zimbabwe or North Korea. PC - not speaking in facts, truths, data, history, nor asking difficult questions - is disarming us mentally and physically.
Is PC about not offending someone else, or not believing in yourself? Are we as a society so hollow, so empty? As Evan Sayet put it, for liberals "A moral thought is an act of bigotry." Is a moral assessment of evil bigotry? Can I not say that rape, murder and paedophilia are bad and wrong? That totalitarian government and intrusive, oppressive, discriminatory overlords are bad for humanity? That islam is not just different, but WRONG. Wrong on liberty, wrong on equality before the law, wrong on nuturing childhood development, wrong its restriction of art, music, human expression? Are my thoughts a crime against humanity? Or an assessment of a theo-political doctrine that is the antithesis of the Western Culture and American Constitution that I cherish?
