I was very saddened when I heard about the shooting at the Unitarian Church in Tennessee, where two people were killed. I've visited Unitarian churches before and have witnessed the warmth and the tolerance that the Unitarian tradition prides itself on.
I was not, however, surprised to hear that it was a target of hate. Unitarianism has pioneered all the progressive causes from the get go. It was among the first churches to become involved in the women's suffrage, gay rights and gay marriage movements, way before the Christian churches did so. This one church had helped to create a local ACLU chapter, and had helped fight segregation. It considers itself a post-Christian, liberal movement.
