Are you asking me why slave owners forced Christianity on slaves? If that's your questions, how is that possibly showing religion to be a good thing in this context? I might just be misunderstanding the question. And I disapprove of it being on the court walls, it snubs the separation of religion and government. My own beliefs are built on what I see of the world and what I learn from trusted resources, and I am willing to alter my view in light of new information, and do not cling unchangingly to disproven and morally inconsistent religious texts. Without religion there'd be oodles less violence and subjugation in the world. Some still, yes, but oodles less.
