John Liddle: Like most Aboriginal males in Central Australia I am sick of going to funerals and seeing our courts, jails, health clinics and hospital filled with brothers and sisters who have been involved in family violence. It is time that Aboriginal males stood up both morally and culturally, taking positive action and a zero tolerance approach to stop the excessive violence in families, communities and towns, a crisis that is having a devastating effect on community members of all ages and genders, especially the children.
