From my - limited - understanding, Native American Communities did not adopt Christianity to the same extent that Slave Communities did. We can see that Christianity is somewhat of a touchstone to the black community, but not to Native Americans. However, in both of their Histories, they were brutalized by Christian forces.
What are the causes, or potential causes, of this difference?
Can't speak to any comparative posts or even posts that detail Christianity and Native Americans, but regarding Christianity among African Americans
