When international conventions come up, it's ok for delegates to be
decked out in traditional clothing from their culture. Surely, some of
those have origins that could be called "pagan." And how is that not
nationalism?
My Wife's JW relatives (white people) are Missionaries in Africa. Whenever they post on facebook or Instagram photos of themselves and the African Witnesses at meeting or in service, they are all wearing western shirts and ties and knee length dresses.
They study their American religion with the African people and make them give up their traditional clothes and make them wear the "JW appropriate" western clothing.
When these same relatives come back here for the assemblies, they are always wearing full on African garb and jewelery. His outfits always consist of a long brightly colored tunics and loose pajama like pants and a little circular cloth hat on the back of his head (even during the prayer). (Ever the smart a***, I always ask him why he isn't wearing a bone in his nose). She always has a brightly colored long wrapped dress over loose pants and huge matching headdress. The clothes are nice but they look ridiculous on blond people in a western U.S city, especially when they go somewhere to dinner. Talk about drawing attention to yourself.
Anyway, as far as banning things with Pagan origins, we weren't allowed to eat "Hot Cross Buns" because they had a religious (Easter) origin.
