:Nazism#Church and state is almost entirely about the relationship between the Nazi regime and churches.  But "The historical roots of nazi ideology" does not mention views on religion at all.  We are  blurring the line between ideology and actions.  We need to use sources specifically about nazi ideology, otherwise it is just OR.  If we mention religion, we need to say something like, "although nazi ideology did not deal with religion, in practice they were pro/anti-Christian and supported/opposed by the main churches" (whatever the sources claim).  But again we need sources that connect their religious policies with their ideology.
