I've observed that jws are a people without culture, or at least cut off from their culture. They cant participate in most expressions of culture because they are rooted in 'false' religion or national holidays. A lot of art and music produced by their parent culture becomes off limits too. They end up mostly dressing the same, and have no rituals that reinforce community and social ties except boring assemblies. The jw cultural artifacts such as writings, art and music are strictly co trolled and issue from one source, like a totalitarian regime, so jws are not creators or arbitrators of their own culture. They are also told not to favour one culture or people over another while given no alternative to forming a cultural or ethnic identity of their own in the context of their society. Also they are not supposed to develop self in areas of art, performance, literature, sports, or get involved with cultural expressions such as parades, celebrations and family activities. they are also to keep away from non jws who do express their identities through their socio-cultural context.
Thus cut off from society at large, the wt can practice almost any perversion of reality, shaping the jws the way they want.
