There are cases of women and children being used as mule's to carry and sometimes detonate incendiary devices. Sometimes even without their knowledge. The reasons for extra screening, is based not only on race, but on other interactions with other security staff at the airport. In short, why is it a surprise that passengers who present a potential, but real risk, to others, would receive dispensation. Why should a society at real risk of lethal violence, daily, sit back and allow such violence to occur. Perhaps that racist bigot comment of yours deserves a look in your own mirror.
