Unfortunately, very few Freepers are willing to have a civilized discussion. As a Freeper since 1998, I and other Wiccan/Christians have learned to keep a low profile.
It is rather sad, since people like me are often caught in the middle. New Age "liberal" pagans hate us, and Christians often call us God hating Satan worshipers.
One of my methods of identifying the Celtic influence upon Western Christianity, is by comparing the beliefs of Roman Catholic with Greek Orthodox.
Many friends in Bulgaria have been extremely valuable in helping me to understanding the differences. The Celts did not have as much of an historical influence in Eastern Europe, some of the differences may be attributed to the incorporation of ancient Celtic beliefs.
