Church Surrenders Moral Authority - Christians Are 50% Pro-abortion

With the exception of evangelicals, the peoples from every other church tradition are between 50% and 60% pro-abortion. Why did the churches surrender moral authority on this issue? The Church has an obligation to excommunicate those who knowingly support the killing of innocent children in this country. This was the Christian commitment dating back to Pastor Ambrose and Emperor Theodosius in the 5th century. What are we saying when a church in New Guinea won't take a stand against cannibalism? What are we saying when a church in America won't take a stand against abortion? What are we saying when a church that meets in a prison won't take a stand against bank robbery and serial killing? What are we saying when the church won't oppose the female draft?
