Jesus never said a word about abortion so being anti-choice has nothing to do with Jesus. Jesus said to love one another, to love your enemies, to care for the poor, to feed the hungry, to heal the sick and be kind to the stranger and foreigner (Good Samaritan.)
Anyone can easily recognize who actually follows Jesus—and who steals His name to promote their fear, anger, bigotry and hatred. People are leaving the church because the church has left Jesus.
