Bias is a disease we pick up from our surroundings. We can control it and compensate for it, but we probably cannot be healed of it. Women and children still experience this. Among others who do are refugees and migrants, persons with AIDS, the disabled and racial, ethnic and religious minorities. The Reign of God is as big as eternity, but it has no room for discrimination.
Discrimination is a terrible sin because it denies creation.
The truth that God made the world in love is not threatened by science. It is denied by those who treat others as if they were not children of God's loving creation, God's Kingdom. Instead, he was angry when he saw his disciples discriminating against the children. The first step in conversion is to recognize our sinfulness. I must examine my life and attitudes.
