this is defined as judgement before knowing the facts. Jews, Arabs, Pakistanis, Chechens, Irish etc. must be guilty because we all know how Jews and Arabs etc. are terrorists etc. Get a Life! Stop this poisonous thought circle spreading further! Take everybody as he presents himself , maybe good or bad, don't condemn someone or elevate him from some vague idea about origin until you know whether he is good at heart or not. You will be wrong invariably if you dont!
