Interesting! Is there a chance for paganism to survive?
Doubt it, these Christians might be for forgiving but they are still going to favour fellow Christians so the economic benefits will cause conversions as well as missionaries. Lets remember Paganism is an artificial construct to lump 100's of non Christian religion's together rather than a single faith. The modern pagans blend the bits they like to get religions that bare no real relationship to any of the historical ones.
There is a reason Ireland for example converted without much bloodshed, Christianity was seen in many cases as a better way to describe the modern ( from their perspective of course
) world than the older faiths. Compared to a lot of the older faiths it was seen to speak of hope rather than fear. Early Christianity is a very different beast to the medieval version that had by then absorbed a lot of intolerance, high handedness, corruption and other negative behaviours due to the power of being the official religion.
